As for the original question, I've been doing about $15/day lately. I don't usually have much time for Turk so it could be more, and I can do $20-$25 on those days where I have 4 or 5 hours to put in.
My daily goal is $100 and I make that quite easily some days and not even close on the others (usually weekends). However, I can easily average $60 per day when you take the total over the month.
