Many of the instructors have group rates so you can organize your own age, family, or interest group to take whatever course you choose. There's a guy in SE Iowa who will come to you and give training(don't know how the cost runs).
I guess I'm more fortunate than I realize. After two hand surgeries, I still have numbness but regained a good portion of the strength back. Haven't shot the 44 mag much but can if I want. I spend a lot of time outside both working and right now, trapping and hunting. Today I pulled all my traps and reset part of them which took most of the day. Probably walked 3+ miles with about 1/2 that packing 10-40#.
