High Performance laravel-echo-server

We are currently using Pusher to run about 1000 connections and 30m messages per day. It's pretty expensive. So I am looking at rolling our own solution using laravel-echo-server on AWS. Has anyone had experience running something with that many messages and connections with laravel-echo-server and maybe on AWS? I haven't done any testing, so just kinda interested if it would be significantly cheaper. I have no idea what kind of server resources that much scale would take.

I like the idea of paying a premium (Pusher) so I can just forget about another server but it's getting to the price point where we might want to explore other solutions as we continue to grow.

Thanks!
