Try putting a listing under 'Gigs' on craigslist. Put details in the description about what you are looking for, and let your potential designers know that while you can't provide compensation, you will credit their design work on your blog, so they will get free exposure plus something for their portfolio. I guarantee if you were to do this, you'd have all kinds of graphic design students and amateur designers coming out of the woodwork to help you out with something.
They would probably be more than willing to help with consultation on the blog styling as well if you credited them for it too.
