Hi,
The title says it all. Keep in mind:
1. Must pass W3C validation.
2. Must be done in HTML5 and CSS2 - 3 techniques.
3. Menus must work with CSS, not Joomla! extensions.
4. Site has a Home page and rest-of-the-pages layout. Both look exactly the same; there is just some modules for the home page.
5. A preview, at least, should be done this week (I am selecting someone fast!).
Looking for someone who can do HTML5 and CSS3 for more projects in the future.
