For those kind of costs, I'd print 300 for $1500. That's just $5 a piece. Sell them for $10, and you can afford to give away half of them.

I think this project would make a great Kickstarter. I don't think it would be hard to get 300 people interested in backing this. Shipping is probably going to be the biggest issue; find people on other continents to help you distribute it there. That can save a lot of money.
