Hello Sean,
Thank you very much for the clarification! Since we already have the site and the products up, there won’t be no need for development support for this particular client. So we will almost certainly go with the later option, since all we need is for the client to be able to upload their images to the woocommerce products (different canvas sizes). As far as i understand, using Cusotmization with MyStyle standard rectangle and TM Extra Product Options will allow us to place the canvas size ourselves. That would be 9$ per month, right?
Thanks,
Andrei, Developer at Musket
