Creating a online game is not a easy task. I have created a login system and player(s) dialog for a simple online racing game that take me months of frustration and it still does. Maybe it's just me, but I think you need a team.

That said and thinking about that this is the Jobs Wanted forum. You should ask a moderator to move this post to Jobs Offered instead and maybe warm the other members up a little with more details about the game you like to create.
