canada

Hello, I was wondering if anyone can please give me some advice on how much a nail technician course should cost? I am in British Columbia, Canada. I came across 2 schools and they range from $4000 - $6000 for a 400 hours course. Is this the normal rate? Or any recommendations? Thank you in advance.

I'm looking into opening my own business and was thinking about renting a chair out. is it better to charge a flat rate, or charge a mix charging a flat rate plus commission, or just charge commission. how much do you charge in either of those methods.
