The last week that I worked a "full-ish" week (over a year ago, before it stopped being my main source of income) was just under $750 for 21 hours of online time. I worked 6 days that week. >$30/hr was typical around that time. When I started doing it, <$20/hr was a bad day and $25 to $27/hr was a good day. AFAIK I didn't break $30/hr (even once) until over two years into it, but it then became a regular thing.
