Personally I have no knowledge of your area, as I have never been there, nor have friends there, but I love a good Google search.
If you are in Johannesburg,
North South Africa as I assume (but of course I could be wrong), here are a couple of search results that might get you started.
http://www.soapbarn.co.za/contact.htm - click on the map to see if that is close enough for you to go talk to them; they might recommend someone who can help you live and in person
http://www.aurorasoaps.co.za/contact - click on map to see if this one is close enough for you to go talk to them and ask for a recommendation
https://www.willowsoaps.co.za/contact.htm - click on map (etc. same as above)
https://naturalnerd.co.za/soap-bar/ - next soapmaking workshop in JHB is Sept/Oct 2018 - perhaps you can call and ask about this workshop and see if it's affordable (if not, keep looking)
By doing your own search you are more likely to pull up results more pertinent because you live locally. At least I find that to be the case if I search for things near me. But hopefully if I understood where you are, these links might find you someone to contact or at least give you a lead.
I agree with the above posters who recommend watching soapmaking videos. Some are good, some not so much, but Soaping 101 and Soap Queen are both pretty good. The only problem I have with Soap Queen is her use of glass to mix lye soap. Lye etches glass and will over time at the most inopportune moment cause the glass to shatter. So I don't recommend mixing soap made with Lye (caustic) in glass.
Here are links to the YouTube Channels for

Edit: Strike-Out
North because South was the correct word. Not sure why my mind went to North when all my search results show South Africa on the maps. Must have been confused by the word North in the OP. In any case, I hope these links help you find what you are looking for. If not, keep looking.
