I've never sold anything on eBay, but there are companies that specialize in taking your stuff and auctioning it off on eBay. For a percentage, of course. I'd check their anti-fraud policies carefully, but I imagine it would be easier to use such a middleman if you're not planning on becoming a regular seller. I've heard of AuctionDrop and MooDog; there's a MooDog near my home, as a matter of fact. Hmmm.
