OP, clearly you haven't thought enough about supply side economics in the hobby. 
An hour of time isn't just an hour. Think of all the additional sunk costs associated with a simple appointment. Each client takes an average of 15 minutes of marketing, and probably 30-45 minutes of screening/TCB. Let's make that an even hour. Then let's say that it takes at least 30 minutes to prepare/travel/set-up. Chances, are that its a lot more. Then how much rest do you want between each session?  I'm thinking at least an hour unless you want an assembly-line provider.  What's that now?  At least 2.5 hours per hobbyist not including the session itself?
4 sessions at $1000 but working 14.5 hours comes up to be $71.42/hour. Now 2 sessions at $800 but working 7 hours comes up to be $114.29/hour. 
Apples to apples, what would you prefer?
Opportunity, sunk, and overhead costs!  How do you like them apples!
