The auction house in Warhammer is just as annoyingly time-consuming as it is in WoW. Auctioneer tracks current and past pricing of all auction items and allows you to price your items to sell in a foolproof manner. Make your items attractive to buyers with good pricing while still making EXCELLENT profits.

AUCTIONEER FTW! PLEASE!

Have you looked at MultiAuction or AuctionStats?  I believe one (both?) of them do what you want (or close).
