Beauty is pain

I've decided that this summer, I'd like to get my legs waxed. I've tried using the strips they sell in Boots and not got anywhere so I'm going to go the whole hog and get it done professionally. This brings up 2 questions: 1) where's a good place in Oxford for a leg wax? and 2) how long to I have to grow the hair before I get it done?
