App for iPhone

I am looking for a freelance developer that can build an iOs app. I currently have a demo version, so the work would be to convert what is a demo into a real app. First step is an iOs app, then the Android one will come. The important thing here is the algorithms that need to be developed to make the app functional. This is a linkedin-like community, but just exclusive for doctors. So the idea is to link them through city, specialty, university where they studied, hospital/centre where they work, etc. and help them interact, suggesting people, topics, posts, etc. I am attaching in this project description some screenshots from the demo version, so you can have an idea of what I have, and what I need to be done. Please do not hesitate to ask questions should you have some. Thank you very much.
