Hi there,
I would love to undertake this work for you. I am a 2nd year Computer Science student with 4 years web design/development experience. I am able to produce HTML4/5 valid pages (strict, transitional and frameset DTD's) and also CSS2/3 valid stylesheets. In addition I will also test all your pages across 8 different browsers on 3 different operating systems to test for compatibility issues and browser rendering issues (your website appearance may differ from browser to browser due to different rendering engines).
If you need to know more about anything get back in touch with me anytime.
Good luck for your auction :).
