Another idea!
You could hold a Variety Show, like the cabaret night, but it's a little bit more open to any kind of act--which means you'll get a mixed crowd. If you thnk you can get a decent audience, you only have to charge like a couple bucks, or "by donation" and make sure your cause is known. People will respond to that well.
Also, you know spaghetti is really cheap, and you could do a dinner theatre. 5 bucks for dinner and entertainment! My HS drama club made a lot of money that way. BEST OF LUCK!!!!
