Pro license for non commercial use

Hi,

I need to release an app for an art show that uses Advanced Model Targets. How do I get the pro license? This is very time sensitive as I have to release it to the app stores very very soon. Is there any way to get a pro license quickly? And also is it possible to pay month by month? I am an independent developer and the app is not being used as a product but only as a vehicle for an artwork. This is non commercial use.

Please is there anyway to achieve this? Thank you for all help!
