from the brief above it sounds like you'll be working with young people but presumably paid by adults for it? So you'll want something catchy but not gimmicky, so they trust you.
also not sure if you'll be based where you are for the forseeable future, so i'd possibly only use the location in your name if you think it will help market the business and your not likely to move / branch out.
i was thinking of synonyms of guide:
pathfinders
Pathfinder MTB
trailfinder
trail minders
ps. all this is from someone with no marketing background so may all be pish.
