Professional web2.0 design needed for freelance website

Hi, I have an exsisting freelance website product like freelancer.com. Its design is partially done already but I want to add more professionalism to it and for that i want a very very professional designer who can design some thing very cathcy and professional web2.0 cool stuff like LimeExchange, Freelancer.com, liveperson etc. The job is to design a template. I will give the demo of the product in PMB. Only professional designers with healthy portfolio/skills should bid. Freelancers with normal or average design skills should not waste time please. What i will require is the design(psd) first. and after getting approved i'll require the html/css of it. Remember!! The site obviously does not have 1,2 pages. But most of the pages will share the common layout. 1 more thing, I am a developer and designer too :) just not having time. Thanks. Saqib
