You might try enlisting the help of some civic organizations near where you live, as sometimes they will sponsor good deeds, and we're really not talking about a whole lot of money here. As well, make sure that you get a round trip ticket that's open-ended on the return, because, no matter how you feel before going, you might change your mind once you are in-country, and you'd probably hate being stuck there. Good luck. It's an honorable endeavor.
