Welcome again i replied already in the video thread but didn't want to clutter it with non promotional stuff. Like i see that you have a good arm and your form varies and week 5 video had the best form and there are standard pieces of advice here that are derived from watching for commonalities in the forms of the best players in the world. Also backed up by physics. That have allowed many people to add distance, accuracy and consistency to their drives. I've done a lot of video critiques here and instructed in real life too. Would you like an outside perspective on your form and what you could try to improve your game? The better you throw the better it will look to people that don't know and yet love the sport.
It is not just the flight of the disc that can be beautiful in disc golf. A cat like grace in throwing technique of being smooth and effortless yet delivering tremendous power is something that will impress many that don't know anything about sports. Athletes might be even more impressed.
Looking from the point of view of a Finn in a snow storm with plenty of snow on the ground i'd say you are perfectly located to train your form
I know that Finnish athletes have trained in South Africa after one of their best athletes married a Finnish top athlete and he used his local connections. I don't know common it is for foreign national team athletes to train in SA but there are facilities for track & field good enough for Olympic athletes. Perhaps contacting the administrators in different facilities could get you ideas and contacts to local athletes and organizations that might be interested in getting disc golf clinics from you. They know the culture, customs, people and how to work the system so they might be able to open doors for you and do the marketing of attracting people to get to the clinic.
Demonstrations might be a good idea to introduce the sport. You could get many more eyeballs on the sport in a soccer match or any other sport where the audiences are large. If you can throw a demo in the half time and have an announcement that you'll give instruction for groups sized as large as you can handle after the match and at place x at time y you would reach thousands of sports lovers at a time. Perhaps you could entertain the crowd trying to out throw a goalie kicking the ball. It would be cool if you can throw 330'ish to throw from one end of the soccer field to the other. If there were posters in the entrances to the sports arenas it could be announced that those posters instruct how to get in contact with you so that people can book a clinic.
Playing might be more fun than clinics so maybe you should try to offer that option too. As a fun activity many kinds of organizations from kinder gartens to homes for the elderly could probably use a new kind of activity. It is too easy to blow off an email so walking into the office of PE teachers, decision makers of many organizations sports complexes etc. might work better. I don't know much of South Africa and the cultures in there but they are fun loving people and if you approach them in a manner that paints disc golf as something fun rather than a chore like a "real sport" where you pant, hurt and sweat it might be more enticing.
As you see i should put a stop in here somewhere being a one man brain trust
It's just we've thought of many things and implemented a few here in Finland where we have the second most players in the world so we have many actives that also think of where to go next. So far we've gotten more ideas than those that can put everything into action. Most like to play rather than volunteer because disc golf is so rad!
