Mom Note:
I am moving your thread out to the different forums so you get, hopefully, maximum exposure. Also would like you to think of any consequences (intended or unintended) of posting your phone number. As a precaution, I have edited it out, but PM me if you'd like it back here for the whole world to see.
Have you searched the forums for threads on flying for charities, non-profits and NGOs in Africa? That might be something interesting, but I don't know if it pays well.
