I understand but please keep in mind with VMware just closing the academy this week it is time sensative. So here is a few thoughts for your teams.
Announce a Proxmox College Academy Subscription - Free for the first year for former VMware Academies ($200-$250) a year after that. It's a dig at VMware but worth it. What this gives you is the official courseware from Proxmox to be used in a college setting (the fee is to keep the materials up to date).
You will have to provide a teachers only discussion board (via account verification) where teachers can download the two main class materials
Allow faculty to upload content as well to share LMS content. I volunteer to create learning management system (LMS) quizzes faculty can use for their classes in conjunction with your slide materials for free to get you started.
Labs can be done in the classroom on hardware or virtual box (since the software is free) but the recommended solution is NDG (Netlab) as another college has already made labs with documentation for any current Netlab customer. Labs outside of Netlab would not have documentation to start, I am sure another college would be willing to write those.
So your real costs, open the official materials to educators, create a secure discussion board section, collect $200 after you pass go, any marketing materials you would want. Not a bad ask for getting in on the ground floor of colleges that gives you great exposure to new admins.
Just a random deployment plan...
