Android game

Hi all, I need android developer experianced in game development. Game is pretty simple, there is one charachter who's goal is to collect objects which are falling from the sky. For beginning first version of the game will be very simple but in future plan is to develop more levels, characters, their skills and soo on, so cooperation will be for longer period. Graphic and animation is almost done so programming may start imediately, we will sign the contract and source code will be given to me. I need full asistance with testing and debugging phase. I beliave that project may be done in 1 month, but as I did just apps and not games before I guess you know better, also I need someone with understanding because as I prevously said I do not have experiance with android games. Main manu will have 4 choices: play, options, high score, more with not many options, as I said pretty simple. Let me know, your about your previous work, your offer, time limits and soo on. Looking forward for your bids. Cheers
