Ask HN: Side business – how to get started?

I see so many people doing side projects or business. I have excellent backend data engineering skills in the data analytics space. However, I honestly don't know anything about front end and don't know where to start? I don't feel motivated enough to learn Javascript/Node etc. Frameworks are evolving very rapidly. I am sure how much learning front end will help in day-to-day job as well. I am good at getting things done. When I look at good freelancers they are often charging $50 or more per hour. I don't want to spend a lot of money just to build a website. Do you have any suggestions on how to get started and what are ways to build a side business?
