Another point is that we do NOT tutor Primary age. That has to be done at the child's home with a aprent in the next room and the door open! We only accept GCSE, A level and Undergraduates for private tuition. English, Latin, History. Of copurse at that age parents are well used to shelling out £35+ for driving lessons.
We do of course have a commission arrangement with other tutors for students that we cannot help (Maths, Science etc)
Used to have it as a proper business but not really profitable given the "thiness of the population here and the time one has to put into vetting others etc. so we cut it back to just Mrs S and a few "referrals".
It was not unknown for me, in the past, to lecture to sales conferences and the like but the agoraphobia has put a stop to that.
