Shopify: List product variants/quantity box and send total to shopping cart

Hi there - I need a custom feature on my product page. I have a few variants for one product of mine. I want each of those variants to display in a list format instead of a dropdown menu, with the price/description/and a QUANTITY field for each variant. See here: [login to view URL] When the customer fills out a quantity more than zero for any of the fields, I want the total amount to be added up and that's the amount that shows in the shopping cart when they checkout. I am using the app Evey Event Management to register ticket orders, so please make sure that the new way of doing this will still register the correct amount of tickets when ordered. It shouldn't take too long to add these fields... just a bit more dev I'm comfortable with. I'd like to use this template for all ticketing orders going forward, so please make the process repeatable.
