Write an iPhone Game

We would like to create one game for the android /ios. We would like to also add in-app purchases, and game center (in case of play store: it is google game circles while for apple it is game center). Game should be developed for both android and iphone / ipad. Some of the additional features needed apart from the game itself: 1. In app purchases (where user can get a solution if he/she is not able cross certain level) 2. Game center (game ranking within the android / app store community - trophies + badges etc) 3. Game score sharing features (facebook/twitter) 4. Email to friends / contact support / share via text 5. admob support 6. Game help etc Make sure all required things are modified such as icon, music and images. Please note we need high quality work - so if Icon / images or music needs to be of high quality. We can purchase it separately from other stores if required.
