font preview design and etsy api checkout for woocommerce/wordpress

I need a wordpress plugin that functions like the below website. Basically a page where you can type and show previews of the fonts, finishes, colors, pick options, generate buy buttons and sizes then pick to either add to woocommerce or checkout on etsy the way their site works. Seems to add some kind of virtual product or something not exactly sure how that works, something with the api. www. acustomcut . com As extra add on i would it be add a modification of the product to be able to turn on and off for the designer to be able to upload an image and system be able to calculate the price. Basically the person would upload vector artwork like a pdf and the software can read the exact size of the letters (longest pieces of each letter) . So it would be like the word HELLO, each letter is 5" tall, 5 letters at $10 per inch = (5x10)x5letters = $250. Type jigga55 so i know you read and saw the site. Example of this can be seen here [login to view URL] either as an addon or something seperate but i need to be able to control that feature per product. I would also need to be able to add addon options to that price also.
