Dmshop trabalhos

I have already written a online shop at but is not sufficient for my needs. I would like to use oscommerce but i cannot understand the database usage. i would like to get it running on a localhost before i ftp to my server site. I would like to use access for the database or whatever if it could be set up with a minimum of fields (productID,Category,Product,Price) then i could add,edit,once it is working. i need the lot setup from scratch. Is it possible that someone could do this for me. Regards Dave
