Keep in mind we are doing this with no permits. You don't have to have one, but you have to operate within the rules. One of them is numbers. Hence the 75 people a day. Pretty sure that is standard Forest Service rules. If you have over that number then special use permitting kicks in. The other thing is you can't charge for your services. Donations are fine, but the class itself has to be free. Otherwise you are stepping on the toes of other guide services who actually have paid for the right to operate avy classes on Forest Service land for profit. Since you are talking a not for profit operation, that shouldn't be a problem. Hence why we do all of our fundraising at events or online such as the splitboard raffle currently going on. These are just things you need to be aware of. We took our lumps over quite a few of these for no other reason than we just didn't know. To do what you are talking about should be perfectly within the boundaries as long as you watch your numbers and how you stage the area. I do recommend that you talk with the ranger who supervisor where you are planning on operating. Getting a good relationship with them goes a long way as to what you can and can not do.
