Companions Wanted: Tour d´Afrique Trip: Will help pay travel!

My nephew is doing the Tour d'Afrique Trip. He doesn't want to go with a tour. He's done some amazing, months long hikes and is working with a fire department now. He's a graduate from a well known engineering college who loves outdoors and adventures. Me and my brother are super excited for him, but would love for one or two others to join him. He wants to go around 40 miles a day and have the freedom of not being in a group. We're willing to help subsidize the cost of the right companions. Thanks.
