Looking for an ecommerce plugin with multiple fields

I am designing a site to sell pull out drawers. I’m looking for something similiar to this site: http://www.drawerdepot.com/create_custom_drawer_saveas_combo.php?mycomboid=68&Cn=1

When you add a drawer it places it above the the order area on the same page. I’ve spent hours searching online and can’t find anything close.
Any suggestions would be great!
