I've actually had bad luck with PPS referrals.

I hear you.
The PPS referrals are a good starting point, perhaps a step or two beyond looking in the Yellow Pages, but certainly aren't the be-all and end-all. Like everything, it's a case of buyer beware. I hope you contacted PPS about your bad experience.

A friend of mine got estimates that were as much as 10K apart.
When we did the exterior work on our house in 2000 (which included roofing, carpentry and painting), we had a set of construction specs drawn-up by the Revolving Fund. We got three estimates: the highest estimate was 2x the amount of the lowest estimate! Made me wonder if they were all bidding on the same specs!
We ended up going with the middle bidder because he'd been highly recommended and we were doubtful that the low bidder could really accomplish the project - during the interview, they said they'd looked at some projects on the Eastside to get an idea of how to do the scaffolding for our house. That comment made me think, hell, if the scaffolding is a challenge, what else is?
As for the high bidder, I don't think they were really interested in the project so they just threw out a number to see if we'd bite.
