Hi Rockhunter,
What a good place to go and work !
Speak to Richard Bonham of Richard Bonham Safaris.
He has a great Lodge in the Chyulu Hills, called ol Donyo Wuas. When I was last there he was doing Sand Grouse and Francolin hunts. Also has horses there.
Also speak to Gary Cullen at Hemingways, a great fisherman's hotel on the coast. He has been in Tanzania for ages and is a bird shooter.
Let us know how it goes !
All best
Tony
