Do you have a standard pricing system for your service? If so, please share the details here.
All of my pricing is dependent on a couple factors 1) where the lesson takes place, 2) how long the lesson is.
Location: Lessons at my house are slightly less expensive than if I have to travel.
Time: Longer lessons are obviously still going to cost more than shorter lessons based on an hourly rate, but I skew the rates towards a lower hourly rate for longer lessons to encourage maximum learning.
