CSS Guru for web 2.0 Site Cleanup/Styling

We have a new website that is complete so far as layout, but id like an expert in CSS styling to go through and clean up and make recommendations. The site is mostly styled by CSS but its been done by a beginner to css, and while it looks 'ok' now - I think a CSS expert could take it to the next step .. My expectation is that someone can go through the css files and clean up issues such as font-sizing, colors used, borders, padding, margins and also make a more professional button style - so the site has closer to a web 2.0 feel I do feel this can be done by mostly just modifying existing css and minor changes to html - im not requesting an entire site redesign. The individual will have access to css files and smarty templates. Please provide a bid based on 3 hours of clean up work, and short listed bidders I will then give a url to view so they can confirm their bid and make an official proposal. Please send me samples of your work. DO NOT send me a PM with 30 websites to view - send me a handful of pages on work you have done before.. I wont have time to try to 'figure out' what work you have done on a site - send me specific urls and samples of CSS/design work you have done along with any explanations. Thanks.
