Merge, Normalize, Remove Duplicates Large Data Sets

Two databases needing merged. One database is in multiple MySQL tables. Second database is in 75-100 individual csv files. Each database has approximately 15 million records. 1. Need both data sets mapped into one MySQL database. We will help with mapping fields between both databases. 2. Need to derive and normalize data. We will help providing direction with this. 3. Need to remove duplicates based on certain fields once #1 and 2 are complete. If this goes well, this will turn into ongoing management of this and other databases. So please do not bid unless you would be interested in this ongoing work. Data will be provided via download links. Thanks!
