iOS5 Game Kit GameCenter Framework with very simple games

I have already created a top selling news app and am looking to expand my team. This project is easy, but I want it to be as "polished" as native iPad and iPhone app. I need a VERY talented programmer who has released apps for the iPhone/iPad before. Video with wire frame mock-ups to provide visual storyboard will be sent to successful applicant (if needed). App Type: Simple Game App utilizing the new Game Kit and Gamecenter for the iOS5 : Friends Leaderboards Achievements Multiplayer Voice Chat Auto matching Rate inside the game custom invite sounds . I will need to include in-app purchase as well. iPad: I would like this app to work on both iPhone and iPad natively. The graphics are very simple and this should be fairly easy to resize. Future Projects: We will be adding additional apps as we move forward in this field as well as the addition of game development in the very near future. I will be very interested in having you work on more projects! Please provide the following: 1. Any design/programming you've done before on the iPhone (and iPad). 2. Links to your previous applications in the iTunes App Store. Must Have's: - IOS5 BETA installed - Has released games with GAMECENTER for iphone/ipad previously - Graphics and design skills are a plus - Provides input and ideas for improvements - Enjoys doing their work (important!) - Is available on Skype during US working hours - Finishes work in a timely manner Estimated workload to begin is as-needed per project and will continually grow as development load increases. We only want to build A+ apps and have a blast doing it! Also, I'm a new user on Freelancer, but one of my partners has a 5 star rating on sites like Odesk, Guru, etc! Look forward to speaking with you! Please reply with the job code "IOS5" so I know you took the time to read this complete job posting and you're a real person ;) Thanks Scott Manthey
