Countless startups have tried that... and we still dont have a great way to get accurate recommendations for handymen, maids, mechanics, elderly care, etc... all those where trust and skill are needed. So far I still rely on person-to-person recommendations. Many suggest that Facebook could hold the keys to that particular kingdom, by providing a verifiable online identity. AirBnB is one of those that uses Facebook for that.
