Cubecart mod needed

Mod needed for cubecart script. 4.4.1 price needed and time frame. 1: We need to create a new product “option” that we can apply to each individual piece of wall art we sell in our shopping cart admin panel. The option would be based on the height and width of the artwork that it normally prints in. The height and width we assign will determine the price of that individual item. 2: Example: we add a new product to our store in admin panel that normally prints 30hx18w. We input 30 x 18 and it will automatically determine and display the price of the product. 30hx18w=540 sq inches. 540 x 0.06 = $32.40 Example: Next product 18h x 18w = 324 sq inches 324 x 0.06 = $19.44 or so on…. 3: The “price” and “size” would need to display on the product page., So the customer knows the exact size and cost of the item when selecting options. 4: On the customers end for each product we add we will also need an input box so the customer can select a new printing size if they choose. The input would have to “constrain proportions” just like photo shop. This will prevent us from printing images that could disfigure. 5: Also when the customer changes the size it will also update the new price on the product page and in the cart for customer to see... Once the customer has completed the transaction our shopping cart will automatically send us a new order completed e-mail. 6: The new size and purchase price information also needs to display with other options they chose in our “order and add new order summary” in our shopping cart admin panel. 7: The prices will have to also display in a every tpl / template file, that price would normally appear in.
