Datat compilation indicating Ebay buying patterns(repost)

I sell jewelry on ebay however I sell two different types (lines) of jewelry. I sell fine jewelry and vintage jewelry, however I thinking about segregating into two accounts each with its own particular focus. So, what I need is to see if my customers who buy in a certain category(fine jewelry related categories) also buy the vintage style jewelry (vintage related categories). All of this information is publicly available by going through my feedback. Furthermore, for advertising purposes, I would like to see what other categories my buyers from. This may other types of jewelry or nothing related to jewelry at all such as clothes, accessories, antiques, etc... I would also like to see what the buyers of one of my competitors also shop for on ebay. The ebay name is " [login to view URL] " I would like to see some cross analysis with another ebay competitor. Their ebay username is " bre-chlo ". This can be a very large project or a small one, however I would like some informative data that help me create a marketing plan and help me more clearly define my target market. Please let me know of the ideas that you may have to help me find my result. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
