My experience is that you'll find more front end developers that bridge the gap than designers. Personally, I'm frustrated that the majority of designers won't pick up such simple things as XHTML and CSS when developers are expected to know such a vast array of languages, conventions, and photoshop to boot. I think you'd have an easier time if you specified you're looking for a frontend developer with skills in design. Just ask for work samples, I'm sure they're up to par.
