I'm with Particleman on this. Someone good at reading and understanding mySQL structures would write something in a few days, then run it against how you have your data today and all done.
Look at Prestashop's csv functionality and see if that is what you need. You will need to get your data into csv format (Excel) which is usually not to difficult.
OR learn how to write INSERT INTO mySQL statements and use Excel of something to create the data in the right format to insert into the appropriate DB tables.
