Professional copy writers need not always be experts in your field - they will research the topic and write copy/articles. That could get expensive, of course.
Check content websites in your field, too - perhaps you can use some of their content with appropriate linkage/acknowledgement.
I was thinking of doing the same thing. There is a college just a mile from here so it wouldn't be too tough for me.
You could put in a clause that they only get paid if the work is accepted for the site, which would cut down on the fluff you receive.
