You can hire a bunch of ubbers, including myself and allen, both of us are proficient in CSS so shouldn't be too difficult; although he just had a baby so i'm not sure of how much time he has (although I seem to have a bunch lol).
I don't like using flash too much, in fact, I don't know how to use it too much; but I do know that using it for navigatin can be bad as not all users use flash, and robots can't crawl them; so always be sure to use a sitemap if you use flash for navigation systems.
