Businesses that sell on eBay for you?

I did a lot of buying and selling on eBay in the U.S. I don’t need it so much in Taiwan, but since I like to upgrade my computer things, from time to time I have spare laptops etc… In the past, I’ve been happy to give stuff away when I’m done with it, but it would be nice to have the option of getting a few dollars for it without making sales pitches to friends. I’m unable to use ebay.com.tw, and I’d rather not recruit a friend to help me with that. In the U.S. there are “sell your stuff here” stores that do nothing but list your stuff on eBay and handle the transaction and take their sizable cut. Are their such third party sellers/stores in Taipei? I realize using this kind of agent isn’t economical, but I’m willing to pay for the convenience.
