Need completion of iphone game, I have the graphics ready

Hello, We have the graphics of the game ready plus the main menu and instructions of the game are finish, but in this games contains bugs and need to be completed with all levels/stages. I need someone with experience with cocos2d gaming engine and code resource. The game is all contain only one level, but every stage on the only level is different, so it should be easy for a iphone game app developer to complete this game plus I will be able to give an example. Please contact me for more information
