If your money is mostly for extras, I'd consider just doing ez pandas and god batches while working on something else that you like that might have a payoff down the road. The diminishing returns on mturk are super steep. You can probably make 70% what the average full timer does with 20% the time and effort.
I need to learn all these ways. I struggle to make $50 a week, but also work and full and part time job. But this stuff is needed, desperately.
