In Spanish we say "don't put the cart before the horse", to sell courses you must have authority in the matter and a large number of followers otherwise it is impossible to stand out. How do you achieve that? basically creating a community, you must start a YouTube channel, instagram, discord, etc. and give something valuable to people, share your knowledge and help them solve their problems, interact with your community, while you do that you can collect email and after having at least 500/1000 contacts you can launch a book/course where you go deeper on the topic you master.
