Direct selling/advertising an app for urologists

Im looking for people all over the world to direct contact with urologists/urological hospitals in their area about an app especially designed for urological patients. This app will benefit each urological patient awaiting surgery and I would like to get it out in this specialized market. The app will launch within the next few weeks. If you can create interest about this app I will reward you according to the interest you get. We can discuss about the price. But for each urologist that show interest you will be rewarded.
