oscommerce ebay csv product file import

Oscommerce developer needed for our existing oscommerce store. We need our existing import script fixed or new one created that will import our ebay listings into our oscommerce store from a csv file. The script needs to check our products in the oscommerce store and edit the quantity available if the item exists or insert it if it does not exist. The current script we had made about 1 year ago but it errors on product price. It may be the script can just be fixed or it maybe that a new script needs to be created for this import. The csv file is attached and has about 2000 products. The import will need to be ran on an ongoing basis, daily.
