Script to use internally in excel .csv format -- 2

The script must allow a input file to be uploaded in .csv. Script will work internally and search for data contained on a designated .csv database file that I would like to upload. The database file can be preprepped in different format so you can get the script to work. All data will be exported to an output file in .csv. I need to own the source code and need it to work on Windows computer XP, 7,8 32bit or 64bit. It must be a simple install. You will provide install instructions and support if necessary to ensure the script can work on a computer. I have included samples of the input file, the database file, and the output file.
