What is the purpose of den dues, and how much should they be?

My son is going to be in a Bear den this fall. He has been in Scouts since Tiger Cubs, so this will be his third year. I am taking over his den, for the simple reason that I've seen how a den should NOT be run. The boys have pretty much done the requirements for Tiger and Wolf on their own. Our pack leader is great, however, and he approved this change in leadership. I'm really excited about this opportunity. I want to maximize my time and productivity. Any getting started tips?
