Graphic Design - psd and design for music websites uk

I have a range of websites being developed in the uk with a music based theme covering a range of things, like venues events, ticket sales, merchandising, social networking,etc. I need psd's to be built with really striking graphics for them, i already have arranged their being turned into xhtml and everything else. Anybody who bids must have a portfolio that i can see of their previous work, and it must be good, otherwise its quite likely I wont want to see it. I want the lowest bid that you can offer on a per site basis with changes. If you bid I can give you a full description of the site, maybe some example URL's The person who wins is the person/team who has the highest quality work at the best price Thanks
