I would like to thank you for your utmost professional and invaluable service. My lawyer recommended you but little did I realize the amount of access and how quickly you responded to my legal requirements in locating and filming the person in question. Your evidence will provide the legal testimonial that will standout and help secure my case. Your service has been exactly what I needed to enter the courtroom trial.
