Good start! I can't wait for more. Well if Jack is donating to his old university, what about a sporting goods store? That was the first thing that I thought of since I figured Jack may have been involved in sports at school and he'd want to give back.

Or he could be in computers/software, which would make sense with any regular donations he'd make to the school. Or he could even be in book publishing. There are a lot of few things you can go with. He could be in art and could be donating or loaning a personal collection or family one.
