I started this sport in 1985 as a mere child of 40 and had enough interest and money to get into it. A few took me under their wing but, to most, I was just "under foot". But, nothing would stop me! That is the attitude that a new shooter must have to get started.
So, I think maturity may be one part of getting people into this. It also takes a love of accuracy and not how many rounds you can put down range and the dust cloud you can make.
I spent 10 years trying to recruit people for our club, JSSS. I only found about 10 that were interested enough to shoot in a match. All they had to do is sit down and shoot, I would supply everything else. I think that maybe the biggest part of the equation is, they need to have a competitive sprit.
Like Blindeye states, "where there is a will, there is a way". Besides money being "Traditional" prize, it's also a motivator of the young. If you could say "look how much money you could win", I think it could be a very good "hook" to draw them.
