I think you have the right idea--it is often a good business/marketing plan to focus on what the "other folks" don't/are not
doing. Not only sets you apart from the rest but you are actually offering something useful the others don't.
It also lets you self-select to an extent--instead of getting people that will quickly drop out when faced with harder contact people that are ok with it will come to you.
You still have the challange of the if the market is there for a harder contact school--but it still a good idea......IMO
