De-dupe Three Customer Tables (CSV files)

I have three CSV files that have been exported from a database called US-All-Clients, US-AA-Clients, and US-PLRC-Clients. I need a table consisting of only rows from US-All-Clients where there is NO match in either US-AA-Clients or US-PLRC-Clients. For example: US-All-Clients Alice Bob Danny Phillip Stanley William US-AA-Clients Bob Danny Stanley US-PLRC-Clients Alice Bob Danny New Table would consist of... Phillip William All three CSV files have the same format, and the format of the file is as follows. You can do the dedupe process based on the email field but I want all columns returned in the new table (same format as original): Email,FirstName,LastName,Company,Address1,Address2,City,State/Province,Zip/PostalCode,Country, HomePhone,WorkPhone,Fax, Field1,Field2,Field3,Field4,Field5,Field6,Field7,Field8,Field9,Field10,DateEntered I would like this done immediately, so the first decent bid that says they can do it fast will get it. ## 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?
