Is Google broken?
Short answer is that, currently, no quals are needed by law to teach 'advanced' (ie post-test) riding.
There is the DSA's RPMT qualification. Currently only a couple of providers. This
may - in the very long-term - become a legal requirement.
There's RoSPA's Diploma. High standard 'r/c' type riding required, and reasonable instructional ability (AFAIK - I don't have one).
Pay? What do you want to charge - how many trainees will you get? Hours? Add that to the equation!!!
Daily rates go up to C. £250 for 1:1 road riding. Spend a few hours on Google and see what's on offer. Also, see how your expected level of knowledge, skill, and experience compare.
You may also need to factor in the 'unique selling point' - why should someone come to you instead of another instructor?
Also, look at bike sales and test application numbers . . . think carefully and guess what the future holds.
