51862 delete expired items

i had some work done a few months back where a programmer placed an option in my site that allowed me to remove all expired auctions with a click of the mouse. this has since stopped working, and it's holding up the launch of my site (to do the deletion manually will take nearly a minute for each auction!). i'm looking for a programmer that will be able to correct whatever mistakes have occurred and ensure that this problem never arises again.
