Are you looking for a private investigator in Chicago? Before you hire a PI, make sure the private investigators you use are licensed, bonded, and insured. You also want to have a signed retainer agreement that clearly details what investigative services you are expecting, what the hourly rate you will charged will be, and the budget you will be allocating in the form of a retainer. You can find some of the same gadgets real PI’s use at www.PIgear.com such as live GPS trackers and hidden video cameras. Good luck.
Make sure the detective agency you use is truly registered as a business and authorized to conduct investigations in Chicago, Illinois. [mylinks=chicago]
