Hi Derek,
Nill Toulme amongst others will help you when they see your thread. They really know!
Meanwhile, some ideas. I assume it's ice hockey
Go to the ice rink and find out where you will be allowed to shoot from. See if you can photograph during a practice game or when the rink is used for something else. Ask the coach what they want.
The idea, AFAIK, is to catch each of the kids in some action and at the same time get all the peak moments. You want to arrange with the coach to have the kids line up at the end of the game to take a team shot. Think of how you are going to deliver the pictures. Will you be selling to parents or delivering a set of pictures to the school. Don't end up shooting and then find the consent from the parents is missing! This has to be worked out. Also will you have exclusive rights to sell the pictures to parents or are there other photographers too and will they be competing for your space?
Do you have an account with exposure manage.com. smugmug or some other site that will allow you to sell you pictures online after the game?
Exposure manager, (like the others) will allow you to set your prices and the company will deliver your pictures with your logo on them and conact info as if it came from you and then each month give you the difference between the print cost and what you charge for the orders they fulfill.
Usually it's better to start as an assistant!
Good luck.
I look forward to sports shooters to fillng in the parts I have omitted.
