design and programm an online game

Hi friends, I'd like you to build me a modern and attractive online game website from scratch, It will depend on wwe and such programms but we will be far from owners right, we will not use the same names but shapes of players. the registrer will able to change his character shape and color and name he will be able to make cooperation with friends to play against others, there will be prizes every month to the top players it will be credits he can buy to use some locked features this is first idea, what is your opinion? I also want to make the same game but with new edition for facebook
