I would suggest you manage the project yourself... Your biggest expense is the gunite phase... Try to find a gunite contractor in your area and maybe try to get some rough estimates for a 16x40 pool.
I guess I'm a little nervous. With our house, I knew enough about what needed to be done in order to manage with no issues. Does anyone have a checklist of exactly what needs to be done and in what order when an owner manages? Dig, rough in plumbing, rebar, gunite, plaster, then plumber and electrician to hook it all up? I'm wondering how hard it'd be to find subs in our area who have done a pool build as well.
