Sign price calculator for woocommerce plugin -- 2

Looking to make a plugin for woocommerce with the following features: 1. User uploads a vector pdf. Note it must know how to read that it is vector based not just pdf. Also must have a disclaimer regarding prices for things that end up being one single image and subject to review. 2. Software recognizes all parts of the design and every inch of "graphic" 3. The software recognizes the size and user can adjust the size to whatever they want it to be scaled to. 4. On the backend there is a per linear inch price, meaning for every inch of "image" it adds that up. Example if the person uploads a logo with the words "Hello" the HLL is 4" tall, and the eo is 2" so total inches is 16inches x price = shown price. 5. User can then pick any special add on that ads to the per inch price or flat fee and then add to cart and upload the artwork Here is two samples of kind of what i am looking for [login to view URL] and [login to view URL]
