This voluntary organisation runs projects in Ecuador and Colombia to help poor children to break the poverty circle and to find real opportunities in life. It also offers low cost ($5 a night) accommodation to non-volunteers. But i'd recommend you find a few weeks in your schedule to stop and get to know the country and its people properly. I spent just six weeks there over 10 years ago and I remember it just like yesterday. Amazing experience. Plus you've got Banos thermal baths, Tungurahua volcano and Riobamba market all nearby.
