You might also want to think about the "no price discussion" rule for a moment. Should that apply to everything including strings, straps, capos, picks, amps, PA equipment, recordings, etc., or to guitars only? Concerning guitars, is it all guitars or just new ones? Trust me, such questions will come up, and it's easier to anticipate them and have a consistent policy in place early on.
Personally, I always liked being able to discuss prices of non-guitar items, even when the AGF did not allow guitar price discussions.
