Custom Files? (Patreon)

Here is a loaded question, if I was making a twenty minute file vs a fifteen minute file would you pay more? And more importantly how much more would you expect to pay for 5/10 more minutes (of hypnosis, the pretalk is all bonus anyway).

For the record my customs are $75 and also I am in a place to be taking requests right now so if anyone wants one, I have spaces available.
