Bidding is the best way to get rid of the best contractors, because most of them won't want to invest significant time to compete with others for the jobs, so what you're left with are the most desperate or mediocre ones. And even those will realize in long-term that it's just not worth their time or either leave or perform poorly. So in my experience, bidding doesn't do any good, to either party.
