Area Price Calculator

We are looking to add an area price calculator to our prestashop website. We are a print and sign company so a lot of our products are custom sizes. We need to be able to set a price per square mm or inch for any product that requires it. Multiple products with different price per square mm etc. We would also like this to work with product discounts for quantity and also for specific user discounts. Will this be a module which can be reinstalled if nessecary.
