Totally get it.
I did set uo the same nostr relay on a server as public relay. wss://nostr.hifish.org
Here is the docker container you can deploy:

You will need some linux and docker knowhow.

Yep! I've looked into that, did a little on a VPS I'm not paying for now. I really need to setup a server on something with more processing power than my current side project. But the ultimate way to do it is run all of the services you want on your own linux server
I hear great things about Linode, no experience directly yet.
They do lots of sponsoring/marketing. Have not used it though.
They provide virtual server infrastructure with easy deployable software.
Networkchuck does lots of linode-based (& sponsored) stuff.
