It all depends on how many hits you have approved. A lot of money comes from batches. If you can find good batches, you can make a some decent money. When there are no batches, people tend to do surveys. I would recommend checking out the daily hits thread.
easy I'm not a master but I average between 280 and 350 a week. I've been turking for 3 months now and it has become easier over time. I don't work outside the house so I really don't have time constraints but on average I turk 3 or 4 hrs in the a.m. and the same at night. I stick to batches I know. ex producntrnr, a9's research task, viral, visual genome are my basics. I suggest you get some scripts and get turk alert.
