Send Auto filled Licensing Contract

Hello,
I have a music licensing site that will offer 3 types of licenses.
I am using woo commerce.
In the add new product section I have selected variable product and set up variations for the licenses.
I have set up an attribute named choose a license.
( example )
License contract A =$50 (home use)
License contract B =$100 (internet use)
License contract C = $150 (Broadcast use)
Each license contract type has its own defined uses and is required in order to make a purchase.
I am looking for guidance on how to implement a system that after a client chooses a license contract /music track and has paid, have the license contract they selected be auto filled and sent via email along with music download (also be available in orders/downloads in my account tab.)

Guidance? Thoughts? Ideas?

Thank You,
