Our investigative agency in Florida had a last minute case that we needed assistance with, and we had to find a PI in TN. We contacted Affordable and they were very quick to respond. They have over 20 years experience and are licensed. ( we needed that ) Once we updated them about our case, they were able to start work within two hours. They quickly located the people we were looking for and kept us informed all along the way. Within a short time, they captured all the evidence that we needed on video and still images.
They were 100% professional and easy to work with. And helped us with a short notice case on a busy holiday weekend to boot. We would gladly work with them again on any type of case.

Key People

Robert Sweat
read moreMy career in private investigation began after working for an attorney, which naturally led me to this field. I passed all state licensing exams on the first try, a testament to how innately this work suited me. I believe I just have an inquiring mind. While the work demands hard work and dedication, I genuinely love solving problems. When I'm given a task, I'm as committed as my client to getting to the bottom of it, and I always strive for a positive outcome.
