Develop a Multiplayer Turn-Based Strategy Game for iOS with GameCentre Compatibility

Very Simple Overview - more details and game rules will be provided to the winner after signed NDA. The Game is a turn-based multiplayer strategy game. It is played on a field, where players move around hexagon tiles. The size of the field is dependent on how many players. Playing field is randomized each round. Players take turns to attack each other. Winners gain points and level up characters. Player Stats and Characters are stored in GameCentre. I want to make the graphics simple and 2D for now and i will provide a basic UI for the game. Once game dynamics and framework is complete, a second development will occur to make the game look great - Unless you can propose to undertake all graphical illustration and 3D design in one package at a discounted rate.
