How long it takes also varies.
When I started working for them, I sometimes made like $1.25/hour because I was homeless and deathly ill and blah blah blah and it would take me all afternoon to complete something wroth $5.
Eventually, I was making more like $15-$20/hour.
Something I wrote previously on the topic:

You do need to work at it and get good at it, but it can become a middle class income. I was clear it had a lot of potential upside when I began and it worked within the restrictions I had, so I kept working at it and slowly getting better.
I absolutely haven't yet hit any kind of ceiling. I could still work longer hours, increase my rating, etc. There is still a lot more money I could make. It's just up to me to make that happen by getting healthy enough, arranging my life that way, etc.
