To make sure we understand your question based on the title of your thread, are you interested in simply owning a specific type of pool (plaster, fiberglass, vinyl lined), or shape (rectangle, kidney, etc), or more curious if you and your husband can actually build any of these on your own either as a DIY or sub-contracting it out for others in your area to do? With a little more info, I'm sure our staff and/or forum members can help give you a push in the right direction. 
Hello and welcome to TFP.
In my experience with O/B most subs won't quote you unless you have plans and sub contractor notes. Even then some e.g. plaster and shotcrete won't give you a quote until your project is excavated and in plasters case shot. Honestly, you're in a bit of a pickle pricing O/B on two different style pools without any plans. I'd try to find locals who either did O/B or maybe had a pool company build theirs and use that for a starting point. You could also get bids from local pool companies and then plan on it costing you a % of what a pool company would build it for.
