425637 Navigation menu design and HTML/CSS

Needed: 5 custom horizontal navigation menus designed and coded into very neatly coded XHTML and CSS. Each menu should have a different style. I would like at least one with round corner buttons and one with tabs. The rest are your choice. Each should work across different browsers and should not use HTML tables where possible. The backgrounds should change on the 'mouseover' with CSS. Each should be expandable in size so that it will accommodate different text widths. The menus should contain about 8 generic links and be about 800 pixels wide but expandable to any page width. --> I do NOT need fancy drop down javascript menus but you may choose to do so in your bid. --> I want a PSD source file for each so that I can change the color or gradient as needed.
