Been mulling viability of hiring professors and TAs to give 10 day intensive math and physics lecture seminars backed by tutorials in beach settings. Sort of like taking the lectures of theoreticalminimum.com but on the road, where you can join a session with a small group of ~10 students in places like Barbados, BVI, Costa Rica, mostly outdoors. If the economics can work for for yoga, we can probably make them work for an amateur/programmer interest in math. No certifications, maybe just walk through some coursera and khan material as prep.

Want to teach geeky tourists calculus? If we made math tourism a thing, teachers in host countries could skill up pretty fast as well.
