Clone of an Online Gaming Site

I need to build an gaming website which would be clone of one of the most popular online gaming sites. More details would be available once you provide your profile or company profile. We are looking for preferably a team of good web designers and person who can develop it within given specified time limits. Believe me it would be a feather on cap for a company' profile as far as work experience is considered. So provide me soon your details and examples of good sites developed by you.
