Need information about Jitsimeet

I have a startup idea using Jitsi Meet. I was able to use the mobile APIs to join a meeting. I am expecting around 1000 meetings with 50ish members each (at peak hours) and each of these meetings will be streaming to YouTube.
At earlier stage I am not inclined to host the service on AWS/Vultr or any such hosting service as it will need some capital investment (which I have none right now). So I wanted to know whether I can use the Jitsi server or do I have to host Jitsi Meet to some hosting service. Please let me know about this.
