Hi! We're also looking at a contemporary style pool in the Cypess area. A Link to a thread is at the bottom of this message

We're having a similar dilemma to you trying to find someone that specializes in contemporary designs.

Of the builder's you've listed I know the Pool Man has a very good reputation locally. Other names that appear to be coming up consistently as good builders are:

Cypress Custom Pools
Best Backyard Pools
Atlantis Pools
Hipp Pools
Perry Pools

Cypress Custom Pools and Best Backyard pools both have some more contemporary pools on their websites but like I said all the names above seem to have a really good reputation round here

Hope that helps a little, sorry i can't give my personal experience as we're in the same phase as you and have just started looking at the moment.
