Have you looked at listing your domains with GoDaddy Auctions? I am not sure that posting here will get them sold but I use GoDaddy Auctions almost exclusively for my excess domains, I find it to be a wonderful resource, easy to use and reasonably priced. Additionally they have a lot of ready buyers so that a lot of eyes will get on your domains. I hope that helps?
