Working at health clubs

I rent a room at a local health and fitness club. I work on a self-employed basis, paying them each week for a set time slot. I have to pay whether I use the full slot or not including any holiday weeks. I do my own marketing, but they provide a receptionist to make my appointments. I have to take my own cash/cheque payments, I am not allowed to use their credit card facility. They will, however, put my brochures, flyers, posters etc. up around the club. Hope this helps. Feel free to ask any questions!
