adding database to volusion

Hi I have a website [login to view URL] and I am looking at using Volusion as an ecommerce platform. My website sells ink cartridges and these cartridges will work with numerous printers. I need some one to upload my csv files (example enclosed to Volusion. They have numerous import options but I do not understand them. When uploaded all printers must be listed in manufacturers categories and all relevant cartridges should be displayed for each printer. For example please look at my website www.firstinkjets.co.uk.
