You do not indicate what level the team is. I assume it is not the NHL. But it is safe to assume that nobody is over 30 (and probably much less than that). Who will be paying you? The individual player or a club? Do you need to add travel time to the training time.
How many people will you be training at any given point in time. Are you expected to train position specific? All those questions would determine your level of preparation and thus the time you need to expend.
On the other hand, training a hockey team is a good resume item, and it will expose you to many business opportunities which will be profitable in the long term.
Obviously, there are many questions that influence your charge. Personally, I would not try to get as much as possible but look at it as an investment in my business future. Without having any answers, my gut feel would say that I would charge about 3 times my hourly rate for an individual session.
Good luck. It sounds like a lot of fun.
