Mark, I don't know enough about the subject to know if any of these sites will fill your needs, but I thought I'd let you know about them just in case. These are places I've seen mentioned elsewhere, and just quickly bookmarked for future reference, but I've not investigated them. All, to my knowledge, are free. (Being the pennypincher I am, I can't imagine I'd bookmark a site that actually charged hard money)
