Without closed quals AND staying sane? That's rough. I can just tell you from my experience, I shoot for an hour to an hour and a half a day. Usually make 10 dollars a day. But I have qualified for a bunch of stuff. I've also been invited to do higher paying stuff because of work quality. When I first started it was rough. I was definitely making half to less than half of what I make now.
I've only been active for about a week but I shoot for $20 a day as a goal, been hitting it in about six hours of work passively refreshing the feed. Have yet to delve into the scripts and it could possibly be beginner's luck but so far I'm happy.
