Community based game

Hi, I need an affordable PHP and whatever else is needed -- script designer. I'm making an online web-site run game and I need a beefed up forums system, and simple data communication system for the game. I'm not sure all the prerequisites for the project however they may need to know a few languages such as, Javascript. This isn’t so much a game but a shot at being one of the biggest site-run community experiences ever. The programmer will need to be fluent in the coding of PHPBB for the forums system will use that base. They will need to be able to mass mod it, and what I mean by that, is be able to add the modifications that I want to it. I'm acing PHPBB because it is secure however someone who knows the ins and outs of website security would also be good.
