Are you interested in starting a consulting business or side hustle, but don't know how? There is likely something that you know better than 95% of people - possibly 99% - that they want to know about, could find very useful, or could save them time.

Start posting about that thing regularly; you probably already have content to share. In your posts, direct people to a website where they can learn about your expertise in that area in more detail. This might be a blog, professional page, or both.
