Contractor #2 met with us the very next day which provided a nice contrast. His bid was in a similar format as Contractor #1 except he called out what wasn't included more than Contractor #1. He was friendly and professional. The price made sense (lower than Contractor #1). Contractor #1, later in the week, sent us a detailed spreadsheet with costs broken out. Tile was 20% of the job though; that didn't seem right. Both contractors provided reference information at these meetings. I was going out of town the week of October 18, so reference checking will wait on me to come back (about a week), and visit live job sites.
Postscript 11/28/2011: Contractor #3 never returned the bid! He followed up several times but then just quietly went away. I wish I had gotten 4 contractors so I would have had 3 bids. In the end, 3 bids would have provided good information as the prices between Contractor #1 and #2 were so similar.
