You can probably find someone to make one or maybe if there are any restaurant equipment stores, they might have something? I use a brand called (Maseca)[https://www.amazon.com/Maseca-Instant-Yellow-Instantanea-Amarillo/dp/B0000IJYK4]
What have you been using to make them flat? I was using a pan to squish it, putting it between two books and sitting on it works too, but I found I also had to use a rolling pin to flatten them a tad more.
