As you have experienced it yourself (and as I wrote in my other comment), I think that coming to Africa and see the reality in person is in itself very valuable. We need more people who get a realistic picture of Africa to take home and share with friends.

If there are people who want to do that, maybe I can help arrange things locally. I would recommend individuals only, or families, but not groups in order to allow the visitors to focus on their interactions with locals and not just socialize with each other.
