Too good to be true. His margin on that can't be more than 15% which won't pay for his shop, his vehicle, and gas to drive to the site. Or he values his time at nothing and won't be in business for long. I'd expect any real quotes to be at least twice that for 75 linear feet. That's a HUGE order. At least 2.5 size of a "regular" kitchen. Which means that the price should be at least 2.5 times that of a regular sized kitchen. I'd expect your quotes to start at around 40K for all the bells and whistles that you've described.

I'd be suspect about either his abilities as a business man or the quality of the materials he is using. What brand hardware is he using? What type of plywood and source for the boxes? Are they individual boxes are just one long face frame attached to a wall with plywood ends? What type of finishing and how many steps? Where will he finish these? Does he make his own doors or does he buy them?

Thanks hollysprings. You really seem to know your stuff. This is a family owned business in LA. Apparently, they have been making cabinets for 30 years or so. They built the kitchen for my friend's house which looked great. That's how I found out about them.

I went back to scrutinize my quote based on what you've said.
1) Hardware brand: Not specified. I need to nail him down with some brand like Blum I guess.
2) Plywood and source for boxes: Not sure. Will ask him to specify.
3) They are individual boxes.
4) Finishing: They are charging about $4100 to paint the entire order. They didn't specify how many steps. To my untrained eye, my friend's cabinets look good 2 years out, but I guess that doesn't say much.
5) He finishes the cabinets in his own shop.
6) He builds the doors himself. I think he builds almost everything himself. His factory was in the back, so I heard all sorts of saws working while I was with him for 3 hours getting the estimate. Is it a big deal who makes the doors as long as they are good quality?
