Don't think you can do a DIY in any African country. You must hunt with a PH, regardless of the animal.
Any other AH members think I am wrong, chime in and correct me!
This is not true.
You can do DIY hunt in former French colonies, it is their hunting traditions.
Having said that, challenges are following:
Organize logistics
Get the permits.
Get rental 4WD
Import the rifle (into the unknown country)
Go hunting, handle the meat. (shoot eland and buffalo, then what?)
Speak French language.
Not easy? Correct?
So, you need local knowledge and help. You can call it "PH" or you can call it "local friend".
There was a guy who organized DIY in Cameroun (I forgot his name), he actually helped hunters to go to hunting with local pigmy guides. Price was around 2/3 of formal guided hunts. Unfortunately this person died some years ago. There was a mention of him on the forum, so I made search for him.
Few other forum members with local knowledge did make DIY in Africa.
We have also a community of reputable outfitters on the forum who are sponsors, and advertise their hunts.
But, who will and for what advertise DIY hunts here?
So, it is not easy to work out options.
I have a friend - also a hunter - working office job in Gabon (expat), told him to look around for options, and even him was not able to find options, DIY or non DIY, which ever. Couldnt get any local contacts. I am not sure, how much he tried, but nevertheless.... theoretically and legally is possible
