As I do Permanent Make Up my situation may be a little different to that of other geeks who rent as Nail Technicians....
At the moment I visit 8 salons in my area, 2 per week, each salon once a month. With each of them I agreed what day each month i would visit them and the times I would be there, I gave them a display book to have out in the salon for clients to read through, I provide them with leaflets, posters and any other promotional material I would like them to have.
(A couple have put up other bigger posters and done newspaper advertising but that is up to them)
I pay them 20% of each treatment I do...the day before i am due at a salon they call me to let me know how my day is planned (if i didn't have anyone on a particular day then i wouldn't go to the salon)
You need to decide what would work best for you so that when you are negotiating a deal with a salon you know what you want...back in the day when i first qualified i went along with things that didn't really suit me because i didn't think things through before hand.
