I would recommend signing a builder up in the late summer or early fall, the prices will most likely be better and you should be able to negotiate more. Also they will be able to build 95% of your pool and then just plaster and fill the following spring, that's what we did and I am so glad, our pool was plastered mid April and now it full and ready to go while alot of the other spring builds are half-way done.
Chances are the subs that build the pool won't be as busy either in the fall so you'll get more attention and if they don't show for a few days or so no big deal because you have plenty of time.
