Hi, Tanzania is trying to get less professional hunters, it's to many ph permits for the moment and many of the guys can't find work. Also you must do the apprenticeship for at least 3 years with out salary.... Also it would be tough to find anyone right now that are interested to help you even with contacts !
Zambia is the same story unfortunately, CAR do not have any directly roles so if you do apprentice time 6 month and $100 dollar will probably open the door
but you will not find any work there... Only 2 outfitters in the whole country right now. Cameroon is the same thing not very difficult to get a ph permit.
South Africa would be the best, do the ph course with Chappy in Eastern Cape during 2 weeks, and arrange for a working visa for 4 month, you need a address and pass the general knowledge test, so also the legal NC test, the final day you will do a trophy judgement test with 20 Trophy's from 100 meter by binoculars you should not be off more than 5 percent !!! Shooting test most people will manage, and if you miss you are allowed to do this shooting two more times, if you then miss you do not pass the course and you must do the whole course program again but not within one year !
You must also past the school, that will say the director of the school must put his word that you are suitable as ph, if he think that this is not your thing he have full right to note that in the documents and you will never receive you permit !
After that IF Nature Conservation think that your working permit is enough of if they say you need a permanent resident depend if you will receive your plains game ph permit or not, this is African and things are flexible...
After that you need again do the minimum 60 days with a ph and during this time hunting for 3 of the big 5 to get your dangerous game license, you also need again a recommendation both from the director of the school and the PH you did the dangerous game hunting with, do not forget to take photos of the game !!!
Ok now you are ready, do you think there is a work for you in RSA ?
Unfortunately not my friend, but wish you good luck it's a long road to go.
Also remember that your permit as a foreigner will be a PH permit, to have the outfitter status you have to be permanent resident of RSA.
