Anyone have any resources for finding a substantial scholarship or grant to do an unpaid equine internship this summer (i.e. something more than 1k)?

I would love to be able to work with an equine rescue and equine assisted psychotherapy facility over the summer but they currently cannot offer me a paid position, and as a poor college student I can't afford to just volunteer! It's also many states away from home, so while I can certainly get a barn rat type job at another near by stable it wouldn't be enough to fund all my costs for relocating for the summer. Any ideas?

Or better yet, if you're in the Denver area who wants to offer me a well paid WS position that would allow me to also volunteer a little bit at this other facility?
