Need java help with game (Paying)

Hello, I need help making a game in java. I will need someone to make an extremely simple tower defense game (in java) that uses solid objects to detect collision among graphics. This game will probably wind up looking similar to http://www.jeannettevejarano.com/games/tower-defence.html , but not nearly as detailed. If you are experienced and want to help please add me on msn, [email protected] . Thanks for any help, I can use paypal, rsgp, or WU to pay for your services.
