Auctioneer for Ebay

What i like to ask, is there a Program like Auctioneer but for Ebay?
Reason is because with the auctioneer Mod i went from only having 20 gold to having over 300 gold in 4 days from buying low and reselling.
Any ebay pros out there that can help me?
If i can make 300 golds in wow in 4 days ,why not do it in real life.
20 gold in Wow is like having 200 real USD, and making 3000 USD in 4 day,well you get the Pic......
