I want to start a website that offers short live zoom courses about technical topics. It’s a great way to meet people and learn new skills in a fun and interactive way. What do you think of my idea? Would you pay for a 2 hour course that costs $50? As many as 100 students can attend a course. They each pay $50 each.
YouTube has (non-live, granted) courses on everything. And then there are the specialized course-ware sites. Many of them have a subscription model of "all you can eat" for a fixed price.
Your unique feature is that your courses are live. That is great for interaction with your audience, but can be a risk if you have a one or a few people that like to hear themselves talk, you know what I mean.
Live has also a drawback of necessarily being a scheduled event. How many potential clients do you leave out because their schedule doesn't fit with your lecture times?
All in all, I think it's a good idea, and can be very lucrative, if you find the right subjects and audience. Find that niche and you're golden.
