Welcome to AH.
A bit of a loaded question. It can be done in most countries: Namibia, RSA, Zim, Botswana. I don't know about Zambia and Mozambique.
Namibia and RSA are quite well developed in most respects for Bow Hunters. Make sure the outfitter comprehends bow hunting.
Bow hunting in RSA is taking off with the local hunters.
Botswana is emerging as a market for plains game hunting.
With a new $1500 Bow permit for Zimbabwe it dampens the desire to attend.
What are you looking to hunt?
That will start to limit the locations somewhat.
I tried laying in wait and spot and stallk for Springbok with the Bow. That is pretty tough to do in open country.
Never closed the distance.
Blind hunting is the norm but Spot and Stalk is accommodated more and more.
We just had a property where a tree stand was being offered.
