What's the going average nowadays for the % of pay for a non-employee groomer in your area?

I started at a Petsomething which has always been %50, but they are employees with benefits and whatnot. Since then I've never made less than %55 as a contract groomer, normally %60. In and around Calgary that I've seen it's always been %60 is the fair rate for someone with experience. Is that what you would pay or expect with ten years experience under your belt?
