- I am a spa owner & I have a 3 room setup. I am the only one at the moment doing services. I provide lash extensions, brow shaping ( threading) and facials, peels & LED. I went from room rentals to ownership & haven't had to hire anyone yet.  My question is I have someone who is interested in coming on board as a makeup artist to promote her line & to also do SOME lashes. She is bringing her on makeup line & retail as well as a strong lash & makeup clientele from a hair salon that is restructuring to focus on hair alone. She is hoping to grow the makeup part and pass on lash clients because she is built up an allergy now to the adhesives. I want to add her but i want to be fair in how we should set up our arrangement. re: commission of retail, service commission, room rental etc Thanks in advance for you input.
