from hand to hand

I operate a non-profit with two long term projects : 1 in Kenya and 1 in Tanzania. I have one long-term affiliate who has been in Nairobi working on the project since Feb. 2012. I am looking for housing for this affiliate and for times when other affiliates come to volunteer their expertise. The project involves farmland, planting for sustainability. I've been in business since 2006. The key affiliate staying to oversee the project is a 65yr old white male.
