Doesn't a position like this usually require you to become a full time member of the staff (i.e. health teacher, history teacher, etc.)?
Do you have your teaching certification?
From your past posts, I think you probably do.
Sure sounds like a great challenge.
But it sounds as if you're already doing some commendable youth work.
Do want to leave that behind?
Because if you did somehow manage to get this position, your priorities and time are going to inevitably have more than a little shift.
The at-risk youth work, while I'm sure still important to you, may have to take a back seat to your work as a coach/teacher.
Priorities and heart.
Can you in good conscious give up your current work for this opportunity to do another thing you love.
Whatever you choose, Warpigs, you'll be doing more than commendable work.
