I created a screen-sharing website and have 50-100 users per day, tell me your monetizing ideas

I've built https://shareit.video a while ago just as a proof of concept but people seem to like and use it. While I already have a lot of monetizing ideas, I'd love to hear your ideas! For context, one issue I have to solve is the fact that video streaming is incredibly expensive, so customers would have to pay somewhere around 40$ for around 300 videos.
