I'd start with this forum's "market" section and don't forget craigslist and local classifieds - it's your best bet when it comes to looking for a project boat.
Try searching craiglook / setting up some email alerts - it makes scouting much easier:

of call at (828) 467-3001 and leave a message. Thanks, Bob.
