I want to be a cam girl... any advice, Reddit?

Throwaway, for obvious reasons...
I've seen a couple of AMAs done by camgirls in the past, and they caught my interest. I've got some spare time and could use the fun and extra cash. I was hoping there might be a few Redditors out there who could offer some suggestions on how to get started, what sites to go through, what niches I could cater to, etc.
Thanks! :3
