Mr. Morton is the consummate professional who actually cares! He is an excellent communicator who sent me regular updates as he worked to locate someone I hired him to process serve. His fees are extremely fair and you find yourself wanting to pay him more due to his excellent advice, honesty and diligence in his task. I highly recommend him and will use him again!

I had a need for a private investigator for a very complex matter involving several states and a foreign country. The first company I hired didn't do a good job at all. I then found Delphi Investigations in California. After a brief consultation I hired them feeling very comfortable with their abilities They handled the case in a very professional manner and the results were better than anticipated, especially the part involving the foreign country and Interpol. I highly recommend Delphi Investigations to anyone needing truly professional investigators. Courtnee F. Rex Seattle, WA

I had hired the sheriff's department and to process servers to try to serve my ex-wife divorce papers. She wouldn't open the door and they were unsuccessful. After searching Google for the best process server in Sacramento I called Lance Casey and Associates. His price wasn't the cheapest but after sitting outside of her house for hours he was able to serve her. I highly recommend Lance Casey and Associates to serve your legal documents.

I have worked with Mr. Sanchez for many years. Mr. Sanchez is a skilled investigator and his vast experience will guarantee a quality work product. His experience will often reduce the hours needed to complete your case and reduce the end cost to the client. If your case involves the need for speaking Spanish, Mr. Sanchez is fluent in Spanish and you will save the cost of an interpreter. Mr. Sanchez is very trustworthy and you can be certain your case will remain confidential. Mr. Sanchez has my highest recommendation.

What makes my service great is the customer service I provide

  • 27 years in business

integrity; professionalism; attention to detail; you will know the facts as they are uncovered "not" what you want to hear. There is no benefit to you in a proceeding if you are blind sided by details that should be revealed in the normal course of investigation.


I have worked for multiple companies. I conduct investigations of suspected insurance fraud scenarios and individuals believed to be lying about their apparent injuries.

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.
