I was especially satisfied with the services of Douglas Greene of USA PROCESS. I needed their services related to a custody case in the State of Maryland. I knew that my ex was planning to relocate within 10 days of the end of the month and it was critical to my purpose that she be served before leaving the state of Texas. Because I was not familiar with any of the Texas companies, I went online to scope out some options for process servers in the area. I didn't know one company from the other. I found the Thumbtack site, entered my details and received responses from multiple companies that were interested in taking the job. Although I submitted my inquiry on Thumbtack, I wasn't quite ready to commit, as I was still waiting for my attorney to produce the necessary paperwork. Of all the Thumbtack responses, Mr. Greene contacted me personally, via the site at least three times, inquiring if I was still interested in the services. None of the others reached out to me beyond their initial response (which also none of the others were personal responses, instead just generic responses with contact and fee info). This is where he first won my attention. For me, this struck me as an individual that was both proactive and persistent, just the kind of qualities one would need for the task at hand. I suspected my Ex would be a challenge, as she was anticipating being served and I knew she would attempt to evade the process. I hired Mr. Greene, provided him with as much information as I had and emphasized how critical my timeline was. On the first day after receiving the required legal documents, he made his first attempt within an hour of receiving the paperwork. As I initially anticipated, he was diligent and persistent. He sought after her at her residence, her workplace, her current significant other's residence and even neighboring eateries, in his attempts to locate her. He was even able to identify both of their vehicles in his efforts. He was thorough and tenacious. He provided consistent communication, as he called or texted me with updates at every turn. He kept me aware of his plans and next steps. This was especially reassuring, because I was on pins and needles, concerned about her being served before she was able to leave town. Finally, within a week, I got the call…SUCCESS!!! It was done! Mission accomplished and she was served!!!!!! As an added bonus his rates were extremely reasonable. This was particularly important to me, because I already had mounting legal fees pertaining to my legal battle. As a private individual seeking his services, he provided me a flat fee, where all the other companies indicated that they had additional charges for more than 3-4 attempts, for expedited services, if your subject was not located within a certain area/range and they also charged additional hourly fees if they would need to wait around and stake the individual out. If you are looking to have someone served, particularly if you expect they will provide a challenge, you can trust that Mr. Greene is persistent and tenacious, will go above and beyond, doing everything within his power to get the job done! He's good at what he does.…. a true professional!

This is one of the best companies in the industry that I've ever used. Right from the start, they were honest and upfront and their follow through was wonderful. They didn't just give me a price for service as they had numerous questions to ask in order to provide us with the right type of protection. Unfortunately, they were the highest priced bid we received from the providers on Thumbtack but their service proved why that was the case. The piece of mind and protection we received was priceless. We had armed officers who wore a really presentable uniform and equally presentable bodyguards in suits. They provided security at our office and our home around the clock and the information I have received from the officers was extremely helpful. This has been a really scary time in our lives but they have helped us feel safe. They even gave us what they called daily activity reports with pictures attached so we knew what the officers were doing on every shift and had information regarding things we needed to know. Lights that were out, unlocked doors, blocked fire exits but mainly suspicious cars. One of the officers even called into his office with a license plate and see who the car was registered to. They really cared for our safety and for that we are grateful. I will continue using their services and recommend them to any business or family needing security.

I have known Jason Short for many years. He is an honest and trustworthy man. Jason previously served in our military and as a police officer. He is very knowledgeable when it comes to investigative work. I had a legal office for nearly twenty years and would have recommended my clients hire Jason for any of their investigative needs.

Rory Cuellar fulfilled my expectations in the type of private investigation I was looking for. He was compassionate and worked very well on the personal level as well. His final report was comprehensive and professional. I would recommend him to anyone who is looking for an honest and effective private investigator. He knows what he is doing!

I found myself in a position of needing to hire a private investigator for a child custody issue, and was unsure of the process or how to even begin. Joe was completely patient and understanding, he listened to everything and suggested a course of action that ultimately resulted in me getting the information that I needed! Once we went to court, having the report and videos that Joe obtained helped me win my case! I highly recommend Joe and JPSI!

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

What does a private investigator do?

First and foremost, good private investigators follow laws. Unlike on TV, they don’t break in windows or hack into hospital computer systems to get you intel. When you hire a private investigator, you’re hiring a professional to gather facts and find information for you. Although they can’t obtain certain information (such as health records), they do have access to information that most civilians do not. Often private investigators are hired to perform surveillance or background checks or investigate cases such as adultery, child custody, missing persons, hidden assets, or debugging, and theft or other crimes.

Private investigators can be hired to interview people and provide that information to the client, perform photo or video surveillance, monitor activity at a location where you suspect criminal activities or questionable behavior, track a person’s movements, find missing people, do deep-dive background checks, and more. Private investigation can be helpful if you’re trying to get a court order but need evidence. Private investigators can also help find birth parents. Nationally, the average price range for private investigation is $70-$210 per hour.

What does a private investigator cost?

Private investigation isn’t just for blockbuster action movies. Hiring a private investigator can help in all kinds of situations ranging from finding a birth parent to improving personal security. Nationally, the average price range for private investigation is $70-$210, although pricing often hovers between $40 and $100 depending on the complexity of the services you need. Where you live in the country will affect your costs for private investigation; larger cities have higher business overhead and a higher cost of living, which in turn means higher service rates. The complexity of your case can also affect cost. A basic background check may have a flat rate, while hiring a private investigator to help with your child custody case may require more legwork and research, and therefore cost more. Some private investigators work on retainer. A retainer is essentially a nonrefundable deposit you pay to the professional — meaning you have retained their services — who then works against that amount. Here are some examples of average private investigation costs:

  • Hourly rate: $60-$70; costs can vary based on current fuel prices.
  • Flat rate: $100 for comprehensive background investigation services.
  • Retainer: $1,500 minimum retainer required by some pros before starting work.
