I have a full time job. I instruct one day per week on the weekend, and am fully booked, all the time. My school doesn't expect me to drop everything to do trial lessons during the week because they know I can't make it. They are keen for me to work both days of the weekend because demand is so high, to the point where I am considering going to a 4 day week. I have had none of the issues you describe, Treadstone. Just offering an alternative experience...
