The quotes I recieved from 6 diferent MD pool builders ranged from $6 - $10.50 a sq/ft. Everything in the Balt/Wash area is a bit over priced, just take a look a real estate.

I looked into other concrete people and found some around $5 a sq/ft, but they had never done decking around a pool before. I quess sometimes you get what you pay for in experience.
