Android & IPhone App developer

We are a foundation from doctors working in several hospitals. We need an App (iphone and android) that works location based. Key functionality: patients can see who their doctor is and what his competences are (a sort of resumee/profile). The apps detects the hospital were the patient is (location based) and show all doctors from that hospital. The second functionality is that there will be a section with news items. The App has a back end login that enables us to provide admittance to doctors to create their profile for the app. Doctors will manage their own profile on a pc. And the news items are managed central. We are looking for developers and designers with a proven track record = you have apps in the stores and are willing to provide references to check you are really the developer. You have excellent knowledge of building tools like Jquery, Eclipse or Phonegap. You will do the complete process and uploading to the stores.
