How exactly did you automated this? Isn't it nothing more than arbitrage? Why would I pay you $60 instead of hiring someone's on Odesk for $10?

I think with all of these sorts of outsourced items you have to factor in risk and quality.

Having this very narrow niche lets them really keep the quality level high as they can tweak and QA across multiple jobs doing the same thing.
