Good idea. I've also thought about this for data entry/analysis type tasks. It is fully expected that a worker on any level won't be perfect, especially on these types of services. An approach I've considered is to have have 3 workers do the same task then compare results and take the majority answer which should be close to if not 100% accurate. Overtime you could even rate workers for accuracy and recruit/pay more if possible.
