curveball multiplayer for xbox360

hi i am looking for a game to be selled on the xbox live marketplace. it is a clone of curveball ([login to view URL]) with cooperational multiplayer and versus mode at one console and via internet (up to 8 players/4 versus 4) and vs. cpu play of course. you will need to do the 3dmodelling/gfx- and sfx-work, as well as the coding and the online scoreboard backend for our servers. everything is supposed to be kept pretty simple (gfx/sfx). thank you
