Thats exactly what I do. A couple of friends use my vps and it has many fediverse services running with 99% uptime.
They throw some dollars my way and I kick a share to the devs and other software that runs this place. I‘m also putting in hours to improve the software and coming up with ideas how to distribute the money better.
What we need is better organization. People need to know about this, talk about it and make plans together imo.
