That's a nice short term approach. I would go deeper in my target audience mind and try to understand what they look for online for their education needs, where they look, how they look. Have multiple calls with them to understand it
Among all of that, keyword searches they do in google out of frustration,out of learning, out of alternatives - do deep research on that etc
Then, build solid content around it for SEO basics, in their niche websites area, in forums they follow etc.
In 6months- year, if done well, you should have a consistent flow of traffic + converted folks and also great feedback on your idea from target audience
