I was offered a real good deal a couple of months ago. I was going to rent a table in a salon for £50 a week. I would provide everything, all equipment, products etc. I would also be in charge of taking my own money, I would just have the £50 a week to pay out.
I personally chose to turn it down because I have built a lovely salon with a great clientele and I thought I would lose a lot of my identity. I have to look for new premisies because my salon and some buildings next to it are going to be knocked down to make appartments.
Hope this sheds a little light onto the offer you have.
If it was me, shop around. It's always good to turn people down, they may come back with a better deal. If not, who cares? There are plenty of salons out there wanting good nail technicians. It has to feel like the right decision for you.
