Write a blog post, see what people say? And then maybe if you get a lot of interest you can write a book or do training or just leverage it into getting a better paying job.

I don't think this is a great income opportunity, though.

Best way to make more income is stable, low-stress job that pays you more than you get now. They do exist. Might even be your current job, if you can get a raise. Do some research and see if you're getting paid market rate (e.g. with Glassdoor, or talking to friends).
