Ron Maynard is an excellent private investigator. He arrived promptly for our appointment and he carefully listened to what I wanted him to do for me. That job was to make contact with my ex-wife and clarify a document that she had sent to me which made no sense. I had a list of questions to guide him. And he did a marvelous job of getting the information I wanted. I could not have expected anyone to do what he was able to do. His attitude and mannerisms were perfect for the job he had to do and I have complimented him profusely because he did such a great job. If I ever need a PI again, I would hire him.

Confidential and efficient work. Amazing. Couldn't recommend Arrowhead more highly. I had been having issues with a custody case and my attorney recommended that I hire a private investigator. My friend had met a woman named Kelsey who gave him her card. He said that she was extremely intelligent so I gave her a call. Since I am currently out of state, I was worried about communication. However, Kelsey quickly got in touch with me. We had an initial video call that lasted about an hour. She was creative with how to get the information I needed. I paid a retainer to get Arrowhead Investigations started on an intensive background investigation and two days of surveillance. One night, I got the scoop on some activities that I thought could be useful for the investigation. I called Kelsey at about 1am and she was filming within the hour. It was reassuring to know that I had someone on my side like that. This investigation took about two weeks. Any time I had a question, Kelsey was easy to reach. At the end of this, I received a substantial report and a DVD with footage and photos. The investigation found a few pieces of unexpected information that gave me an extra edge. For my first experience with a private investigator, Arrowhead Investigations was awesome. My attorney was also impressed with the work.

One year after my daughter adopted two beautiful toddlers from a mother addicted to drugs, the natural mother came back with her ex-con boy friend and requested the state give custody back to her. We were devastated as we knew once these precious children were returned to a drug environment, they would have no chance. Unfortunately, the state was on her side and granted a hearing. In great desperation, we contacted investigator Dennison hoping for a miracle. Investigator Dennison patiently explained the process needed to obtain proper evidence to ensure my grandchildren would not be taken away from us. Western Region Investigations worked closely with both our family and attorney and in six weeks we had overwhelming evidence to prove the natural mother and her boyfriend a danger to the children. On 12/12/12, the courts awarded permanent custody to my daughter and her husband. This will be our first Christmas together as a whole family. We can’t express our gratitude enough to Western Region Investigations. If it was not for them, we would not have these precious spirits with us today. - Dick and Barbara Fox

I don’t usually write reviews, but I want others who need help like I did, to know how Hyperion far exceeded my expectations. The entire staff is professional, honest, hardworking, and provided a work product worth every penny. I wish I’d known about this company before I spent tens of thousands on an attorney. A lot of work could have been done more efficiently and effectively had I used Hyperion for some of the services my attorney billed much more for and was unsuccessful at. Hyperion was immediately effective in service of process that was unaccomplished for months when I was relying on my attorney and his process servers. I would recommend them for all your needs in service of process, skip traces, other detective work (just ask - they can do more than is advertised), executive protection, and the list goes on. If you are looking for investigative work, you’ve found the right place with Hyperion.


I find things you want, and I do what I am told, nothing more and nothing less. If you want a job done right, come to me.

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.
