Actually, in both Europe and North America there is really good teams and players who are not in the NHL and the highest leagues in Europe.
For example, in Swedens Division 1 (third highest league), players can get a full time salary for playing hockey – but of course an agent won't help them because they get a provision on player salaries, and they are not interested if the salaries are too low.
So when a contract expires for a Division 1 player, they usually end up in a situation where their only chance to land a new club is through contacts, and that usually means in the same country and/or region. But there is a huge demand for European players in North America, and NA-players in Europe.
So far we have around 200 players, and two dozen clubs. 50% Sweden, 25% US, 15% Canada and the rest various other European countries.
So maybe your target is players in junior leagues or overseas? But then, how do you get the NHL scouts/GMs to join? They are interested in NHL talent, not desperate junior league players with no agent.
It's a chicken/egg problem, and I'm not sure how you're going to get either one...
