I'm working on a web-based tool that makes organizing flight instructors' lives simple - from record-keeping to scheduling lessons - all online.
I'm thinking of charging a small monthly fee to use the services - but I'm concerned about market size. Based on my research, there are about 100,000 flight instructors in the country right now. That's not a huge number, but then again, I don't need a huge percentage of that to make a decent income doing something I love.
What are your thoughts? Worth it? Too small of a niche? There isn't really competition for this, so it would be largely just me at this point from what I can tell.
