My main area of expertise is playing the saxophone. I have created an online saxophone teaching website which is one of my ongoing projects.
However I am struggling for ideas in how to make this niche profitable. I don't have that much knowledge in other subjects to be confident in starting businesses around them.
So my main question is, what would you do if you were in my situation and what kind of website would you create around this niche?
Saxophone reviews? that's my only idea at the moment (potential big affiliate commissions)
Edit: Just to make it clear, I already have a paid membership website which teaches people how to play the saxophone. I am looking for another project
