Its been my experience to "BEWARE OF FREE BOATS", but I would say to watch Ebay, every now and then stuff comes up at a good deal. The reason I say beware free boats is that often you can buy a boat with sails for cheaper than you can buy a set of sails. I hope you find some though, you might also try www.thebeachcats.com, they have a parts section. There might be one here on catsailor.com as well. Also, contact any local sail lofts, sometimes they commision used sails. And last bet, call http://minneysyachtsurplus.com/ there is no telling what they have floating around.
