CSV Product Import

I require help with the import of products to an Opencart eCommerce website. I have added this extension to the opencart site: [login to view URL] The job will entail: I will send you the csv files, you must adjust/amend these files to suit this csv import tool, import the products, send copies of all uploaded files to me and check to ensure all is satisfactory with the newly uploaded products. Number products may exceed 10,000. Maybe ongoing work for right person. If you are familiar up other Import/Export tools for Opencart I will gladly listen to your recommendation about other extension that may make this process easier and ,more efficient going forward.
