Simple iPhone Game -- 2

We need to develop a short and simple game for iOS / iPhone / Apple TVOS - all assets provided as well as direction, very simple game should not take more than a week or two for the right developer, will need to have game center integration as well so high scores can be submitted to leader board as well as two play support through game center. We might port the game to other platforms as well so ideal we would want the development to take place in cocos2d or unity so we can export to other platforms if required.
