iphone App rockstar needed

I have an amazing idea for this iphone application but have no knowledge on building it. There is an app similar to mine, I'd just like to make simpler and easier to use. **I can provide link to similar app, awesome communication every day, and clear directions. reachability is a requirement for the app. I want you to provide graphic design work. it will be based on similar app I can show. I want somebody that's: - an expert developer -can make all buttons on screen consistent -can send a formal proposal -verify status reports every week or sooner -clear due date(June 14th) -adjust application for 60 days after completion -can make a free version of app and also make free version refer to full version in the app. -someone who can get it into the apple store(ask me for keywords) -someone who can get adds on the free app. -someone who communicates well and show me references of your work. Budget$750
