Woocommerce Variable Products

Hi, I am currentlyl working on a printing website for myself, however I’ve ran into an issue.

Let’s say I’m selling business cards, I have an option for 250, 500, 1000, 2000, 6000 for quantities.

Now as a variation that works great, but let’s say I want to add rounded corners base price is 10$ per thousand. I need away to add these variations based on selection without having to do many variations.

I am essentially looking for a plugin that works with woocommerce that is free or paid that can do it. If a client wants to jazz up their card with rounded corners, foil printing, die cut and emboss it would be too complicated logically to do it manually.
