A few years ago I wrote a 180-page technical manual and decided to self publish. Being clueless I started in the yellow pages and got prices varying by 400% from lowest to highest. Eventually I found a local printer with a web press and had about 2500 copies printed for about $2 each in a perfect binding, with a color cover. Everyone thought I was nuts when the truck pulled up with a couple of pallets of books, but we sold them in a bit over a year for $15, with a wholesale discount. Over the next 8 years we did four more printings and the printing cost and sales price went up a bit each time. After selling over 10,000 copies a company wanted to license the right to print it themselves and pay us a royalty and we were only selling a few hundred a year so I licensed the rights away.

So perhaps this would be an option today - find a printer who does catalogs, phone books, etc on a web press and see if they will work with you. It worked out fine for me.
