We purchased a home in Estrella Mountain AZ on the troon course. We did not have a backyard and bid out our project. We sent out our solicitation to California Pools, Cameo Pools, Rondo Pools, Paddock Pools, Dolphin Pools, Presidential Pools, Shasta Pools, and Pioneer Pools. We spent months back and forth in selecting a company. We live in Oregon and this was a very difficult process because we needed a company that we did not need to micromanage. This was $100K project so it was a big deal for us. I even implemented a blog outlining the project and everything that occurred with the process. You can find my blog at blogspot the address is World Wide Web azpoolproject.blogspot. COM I hope this helps.
