Social Network Web Site Design

I need a web site design for a social network platform. The main theme of site is "soccer". Users of the site are soccer fans. The design must be clean, i do not want any flash or silverlight applications. Just html, css and javascript. Site has 4 main categories; - News - Teams - iddaa (web based game) - arena (a forum-like application) Design can be a mixture of facebook and [login to view URL] for all main categories has sub categories. For instance when user clicks Teams, the team names will be displayed at second line of menu. But i don't want a 1-to-1 copy of mashable, main theme must be inspired from facebook but menu must like mashable's menu. The site has more than 5.000 daily visitors so the page design must be optimized for heavy load and it must be easy to understand and use. The colors of mashable's menu can be used. But i am open to different color scheme suggestions. I require the following outputs; - original psd file and used fonts - sliced and exported html, image, css and javascript files.
