AJAX nav bar and body

I need an ajax bar and body for a website. EXACT NEEDS are shown on this example: [login to view URL] Login with username "admin" and password "87e2f8" I need an ajax bar that performs just like that, but doesnt look exactly like that, and a body similar to that below (with the brown and right tables), but also a different look - so no one can look at both sites and see too close a similiarity.
