In reply to tcashmore: Hi Tim, there are lots of options as I'm sure you're finding out.
It depends a little on what exactly you want to do or get out of a course. Do you have any specific goals?
An intro to off-piste would suggest that you're new to it, so I'm guessing that a ski teacher would be the way to go.
I'd be happy to help out, you can find out more details here - www.tinderboxskischool.com
