Printing order price variables need to change with QTY

[canadasm]

- I have invested in having a printing website created and used virtumart as the Ecom platform but I have run into a serious issue trying to figure out how I can add product variables-  for instance if I order business brochures and that has a QTY and a price - now I have ot add paper stock and finishing variables that are dependent on QTY  how is this done, please look here - http://www.printandposter.ca/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=34&virtuemart_category_id=4

how do we set this up correctly?
