Beta, here is my advice to you since it worked for me and still works even though I am out of school...
Host a card game. You’re in college so there has to be 3000 guys at that school who think they should be on the WPT. Host a Hold'em game with 20 guys. Have them Buy in for $50, you take 10% off the top for hosting it. That is an easy $100. Or you can have a limit game like $2-$4 and charge each player $2-$3 per hour for the right to play at your "newly formed casino." It is easy money. You have 2 weeks so you can easily host 5 games. More than enough. You have to know a bunch of guys. Try to get the rich kids who are bankrolled by their parents.
I have a game every Thursday night. It started out with 6 guys and is now up to 25. We use our local Sons of Italy Club. It is a $100 buy in. $100 goes to the club for hosting it, $200 goes towards a tab that we start for the players to drink, I get a $100 and a free entry for organizing it. This is the sort of thing you have to do. Trust me. Just don't get caught. But if you are a JR, you should be out of the dorms already.
