Hi sliv, I would lok for that kind of advice on a biz site - as for contracts and booth rental, in my salon I charge the stylists in my salon a percentage of their takings (20%) but also a min ammount each day also.
The reason I do this is so that one stylist does not hog all the new client's. Also the stylists are responcable for their own stock of colours ect.
I as the salon owner pay for all the insurances, and utilities ect.
Hope that helps in some way
