311231 Patient D'base Program ASP.NET

I will be needing a simple patient database program, with registration and logins. Patients will be able to register - put their info and choose their doctors. Doctors will be able to update info on the patient - sickness/analysis etc. I just need a simple project without any designs, I need this as a proof of concept for another project. Please respond with demos. Bid or ask for more info. Thanks.
