Startup Idea : Doctors on Web(DoW)

We have WoW(Workers on Web), then why not DoW(Doctors on Web)? DoW will help the patients find the doctors nearest to them and fix an appointment with them via an app. Doctors will have their profiles with their exact location so that they can be contacted. While they are visiting, app will keep on updating current location using GPS/Mobile Data. Wanna work on this with me? Drop a mail at sahildua2305{at}gmail{dot}com
