I know that I keep sounding like a broken record, but Earlham College in Richmond, IN has given quite substantial amounts to international students (in addition to being all-round wonderful!). Macalester also has a reputation for being very international, so it may be worth a look there. Check school's percentage of international students; the higher the number, the more I would suspect that money was offered. Also, try for the schools that are ranked a little lower. 1) Because rankings are stupid and 2) because those schools may be getting less interest from people who are applying from abroad and not considering a very wide range of schools.
As always, Loren Pope's books are a great guide. There's a website if you google "Colleges that Changes Lives." Yes, I know that's a cheesy title. Good luck!
