An online multiplayer game script

Looking for online multiplayer (avatar chat) script I'm looking for an online script for a multiplayer chat browser game which I can customize with my own graphics and stuff. Basically I just want the game to be an online chat game with some sort of ability to buy items (which they buy with coins or credits which are purchased with card/paypal ) and trade them and perhaps put them in your room., something similar to fantage, habbo or something such as this. Ideally, a player will be able to register, customize their look and explore the chat rooms, and maybe take place in other things, whatever your script has to offer. If you have made anything like this (I dont care if it's not unique, as long as I can customize it and It's not infringing anyone's copyright) then let me know here, as I'm willing to pay for a script that's the right one. Providing a demo would be great.
