I see no one has helped you with this question yet.  The Best I can do is Nantahala Outdoor Center in Bryson City, South Carolina.  This is a top draw outfitter and they can put you on a number of rivers including the Ocoee, Nantahala, and Chattooga depending on your skill level.  My personal favorite was the Nantahala.  It was challenging but not terrifying.  Their web site is www.noc.com. Good luck and watch out for those rocks!
