I love what you’re doing by the way! Here is an unsolicited idea. What a lot of people in India do now is they do micro loans. This is where you provide about $1000 for people that want to start a business (like buy an auto rickshaw) or go to school. It’s massively beneficial and a bit more sustainable from the provider’s (your) perspective and you can help an order of magnitude more people. Maybe something to consider. That being said this works in India because it is a very very cheap place to live in. Africa on the other hand from what I know is both poor and expensive at the same time.
