I want to help you so I'm going to be honest. I don't think its a good idea. Maybe i'm not understanding it correctly but how i see it is that this is AirBnb for haircuts.

If so i think there is a contradiction. I think there are 2 types of people who get haircuts. One that goes for cheap and other goes for quality. Both of these are achieved by picking the right salon. Thats why hairdresser works with the salon...

I dont think future of haircut is to remove the middleman of salons. Salons are essential.

I hope this helps.
