Amazon Listing Clean Up

I am a marketplace seller on Amazon.com. Recently I had a programmer create a series of "false listings" in my inventory. Unfortunately, this programmer may not be able to help me further. What I need is a "cleanup" of these listings. I want to have only up to 5 listings per product/isbn (books). So, I need something that will scan my inventory and eliminate any listings in excess of 5 per product. Speed and quality are my primary concerns. What I pay to get this done is secondary. I'm looking for someone with experience and who communicates well. Thank you. ## Deliverables One way for this to be done would be to do an open listings report from Amazon and then edit it using the program created by you and then uploading the finished product without the duplicates. If there is another way to do it I am open to that possibility. This needs to be done quickly if at all possible. I will pay for quality and speed.
