Custom Wordpress Calculator with Add To Cart

I needed a custom calculator for Wordpress that lets a customer input height, width, quantity and upload an image. Then they can add that to a cart and checkout. I was hoping to use the Wordpress platform. I do not yet have an ecommerce solution but there are several I was considering that integrate into Wordpress. Here's an exact example of what I was looking for. [login to view URL] The gray box with "height", "width" and "quantity" with a calculate and add to cart button.
