Tomlin Leckie teaches blues harmonica online from Edinburgh 
Talking about his tiny niche in a 2020 interview…
This is an instrument that you don’t hear in the charts – and yet I can earn a living doing that because I can have my 500 students around the world paying me to learn from me.
Back then the school cost $30/month. 500 paying students works out to $15,000/month 
It’s $39/month today, and I suspect he has more than 500 students.
Tomlin’s funnel: Free lessons on YouTube (260K subscribers), free tabs to build an email list, then the paid online curriculum.
Took him 3 years to earn a full-time living from the business.
Goes to show that you can make good money doing pretty much anything online so long as you stick with it long enough.
Other examples 
- Christine Tyler Hill: $14K/mo via a handwritten magazine about life as a crossing guard.
- Salaryman Tokyo: $3K+/month filming his boring office job in Tokyo.
Pick one niche thing that you’d like to teach or document, and stick with for the long haul.
