There are several reasons no one has responded until now. First, no one is going to code something for you unless they are getting paid for it or on your team to start with. Second, you didn't mention what language your game is going to be coded in, it's hard to make a site for it if you don't have the details like this one. Lastly, you didn't mention the language you wanted for the site or provide other useful details like how far along you were in making your game.
In any event I have a site with my Java game running on it but without knowing what language you game is in there's no way to link it. I would provide tutorials to help you but can't due to the lack of what I mentioned earlier. Have Fun. ^_^
