Great niche training venture!
Have you maybe also thought of a new product nobody has applied that I know of
but kicked around with friends: some (many?) for numerous and sultry reasons
may never get around to upgrading themselves but would both appreciate and
also be challenged to grow into a possible course consideration via, or through
a "product" along the lines of a low-fee based couple of hour long, rap session
held somewhere, whose focus would be "overview" review of some core applicable material?
It would be along the comparative lines of what Bernie had done a few years back
in "packaging" some core basics on Motorcycle Maintenance, and had great success
with attendees: he made his money, the attendees walked away if nothing else,
more confident to keep spilling their oil when doing oil changes but now in a
different direction, etc. (!!!)

Anyway, this kind of thing might also bring you additional income from a target audience of
riders that otherwise won't or don't do anything else? Not sure if that makes sense but
that's the basic idea for your consideration, and disposition!

(Hoping thereby also
to help your great business !)
