custom database

We require a database built that will do the following: We daily input excell records, giving client name, address, phone numbers (some times), various financial data into a master table(?). We need program to find duplicate data, as we obtain our information (public records) from different data vendors. After filtering out duplicates, we need to run our phone-number appending program to all records without phone numbers. ## 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. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform We are small office, XP, nothing fancy. We have seen a similar database to ours in ACCESS.
