Hi geeks, i would like some advice. I have a room in a hotel which i run my beauty salon from full time. I would like to rent out my room to a friend?/ therapist for 1 day a week, which would give me a day off. She would be doing the same beauty treatments as myself and using my products etc.. Should i ask for a set rate for the room for the day or work with percentages, what would be recommended? She would be bringing some of her own clients which she normally works from her home, but also clients from myself and the hotel, i have been established for 3 years in which i basically worked everyday to build up my clientelle from scratch. i have a lot of advertising costs with my business (phone directories, website). I only have the 1 room so there isn't a possibility of extending the business. Please help!!! I want to make sure we have a fair agreement between us.
