I am interested of self-hosting my own instance but one the issue I have is:

• Price for renting server and buying domain name. Mainly, I have low income.
• Unsure if it be single-user instance or if I want multiple people on my instance.
• If my instance is for multiple users, if I be the best fit for moderation as well, pitching it to non Fedizen (whatever you call people that use the Fediverse) as well as the theme of the instance as it would effect my Fedi software of choice (eg. Friendica, Mastodon/Glitch)

I just worried that I try just do it immediately without planning things out or have whatever things in mind which might otherwise help me know what's the best choice and not be upset that I wasted my time and money on something that didn't work out for me.
