I have an independent contractor that wants to rent space in my 1575 square foot studio. She would be utilized 750 square feet for classes up to 10 utilizing TRX straps 8, RIP trainer and tons of functional equipment that will be subject to wear and tear. She wants to pay a flat rate for 9-11 classes per week. Should I charge a percentage or a flat rate? In Nevada I think trainers are paying around 15 to train in a gym setting for one client. I have no idea what to charge or how to calculate the depreciation or replacement rate of the equipment. I need to find a contract to write up and am having a hard time. Studio owners what would you charge and trainers what would you pay? I am promoting this trainer and paying for mind body software for booking etc.
