Multiplayer and single player java pool game

I want an online pool game made in java, very similar to Jippii's old pool game. I want to have a chat room (made in java) where users will go to talk to each other and can challenge people in that chat room to play pool. The two users should then enter the game and play pool against each other. Once the game has finished they can either replay each other or return to the chat room. I want this to be done in java and will pay a maximum of $800.
