Why don't you go to other gyms and talk to beauty therapist about the business that comes in through the door etc... do your homework and be realistic about it. I rent two rooms, a small area where I do my office work and a reception room. i pay £330 inc rates and utilities. the salon is within an independant department store in the high street. I thought that being in a store would brind in lots of clients especially as I am able to put fliers in shoppers bags and advertise in store, but in reality i get very little from the store which surprised me. Don't bank on the thought that being in a gym will generate clients. i had a friend who paid a lot, like you, and had no clients as gym people tend to come in do their fitness and leave. Be careful and good luck
