Trying to do things 100% properly isn't necessarily good.

I know it's sort of a difficult shift in mentality especially for anyone with a programming background, but not doing anything at all for fear of doing it incorrectly, or delaying doing the thing because of all the setup seem much higher risks to me.

In my experience, you can just start doing the thing. It probably won't make any money anyway, in which case you can just stop. If you make some money, then you give some (say ~$1k) of that money to a bookkeeper who will then figure out how to declare it properly.

I get your fear though, as I used to have it. But this world is not like an API call that completely fails if you have one thing wrong. Instead it's people, who talk with you and figure things out with you.
