You have heard of outsourcing to lower costs to testing. But have you heard of crowdsourcing? This is a new spin where a company has independent testers all over the world. You company contracts with the umbrella company to get your tests executed. You only pay for defects found.

This method has the advantage that you do not need to set up the outsourced testers. A company has already done that for you. You also only have to pay for results you verify. A test cycle can run you as little as $5k. I just wonder what quality of tests you can get for such a small price. It could be worth a try.
