Multiplayer games for joomla

Hello there, I need 3 things: 1) Conversion of JG Chess multiplayer game from joomla 1.5 to joomla 2.5 (linik: [login to view URL] register first) I have bought this component and can give it personally (no commercial use) in order to convert it 2) Create a backgammon Joomla 2.5 game but for multiplayer gaming. Classic backgammon game that someone can challenge another player (concept like JG Chess that you challenge someone and wait for another to sit to the table and play). I needs to be integrated with joomla users. All the concept will be like JG Chess 3) Create an 8 ball or a "full-ball" (i think its called American) billiards multiplayer game for Joomla 2.5. The concept will be like JG Chess again. Please give a price for these 3 projects and/or seperately for each project and estimated delivery time (as soon as possible). THank you in advance
