CSV product import to virtuemart

I have a website that needs product import, the CSV files are from Brands distribution, they need to be put in to the virtuemart shopping cart system, they need to go in to the correct categories and subcategories i.e {mens - shoes] or {women - vests} Etc CSVI pro is installed so for someone that knows that they are doing this is an easy job and will not take long. They will need to make a product listing complete etc and then export this csv and they have their template to work from. It will be a matter of mapping the brands distribution csv for import. There will be no need to worry about product variations, this can be added to each item later. The brands distribution csv is attached, if you know virtuemart then you will already be able to see where the changes need to be made.
