Actual Customer Testimonial

"Excellent service, fast and efficient!! I am in California and needed to locate someone who is very hard to find in the Houston area. John went the extra mile for me, and the best part was he under-promised and over-delivered. He laid out exactly what he was going to do, and said it was the most economical way to go. He even had his uncle check around for him, with my autorization of course! Needless to say, I got results. Even if I hadn't, I still would've been happy with the professional, honest, and courteous service I received."
