Newbie about to build a pool!

Hi everyone!

My doctors have told me I have to do water therapy every day, so I'm starting to get quotes for a pool in my back yard (see how I made that leap from "have to go swimming daily" to "would love to have my own pool"?!). I don't know if we're going to be able to afford it, but I'm hopeful. I've no interest in doing this half-a***ed, but neither do I want something enormously extravagant.

Would it be alright if I posted one or two of the better quotes, so someone here could give me advice as to what I may be missing, or otherwise "heading down the wrong path" about? Any advice from this experienced forum would be deeply appreciated and, if we do go ahead with the project, we will gladly post pics!
