Direct advertising/selling of an urological app to urologists

Im looking for someone that can help me promote an app for urological patients. If possible i would like to get someone that will do direct marketing in their area, go directly to urologists and print a brochure for hand outs for patients. Or a poster that can be put up in their consulting rooms. I will pay for print work and will pay for each urologist that you visited. I will send artwork, but will need pictures to proof that you visited the urologists. I really do hope i get interest in many different areas as i would like to do promotion in as many areas to as many urologists as possible.
