How to set up: Limited quantity custom item with variant pricing

[TomCCC]

So, I'm in the process of getting the site for my best friend's business rolling and we've come across something we haven't found a solution for.

She makes custom items and wants to have a limit of 10 orders at a time, but options will obviously affect on price.

With the default template I can set quantities per variant but not a total quantity with variants.

Do you guys have any suggestions to have a total quantity with added options that will affect price per order?

Please feel free to ask any questions for clarification.
