here is an update...
we have ordered from Royalswimmingpools.com and they have been great about answering questions and responding quickly and pleasantly. Johnny, from Royalswimmingpools.com was very helpful in technical questions and was able to price match with other suppliers.
we ended up with 16x32 composite vinyl lined, standard depth, 40" to 8 feet deep end, approximately 20K gallons, Pentair intelliflo VS 3 HP pump (I know its over sized, but allows for expansion such as solar panels on garage roof, etc., Hayward c 4030 400sqft cartridge filter, aqua-rite 40k salt cell. 8' roman steps and 8' cozy cove swim out.
my buddy has a backhoe and he and I are going to excavate, I know could be trouble, but I think I have a pretty good idea of finish elevation and I bought a rotary laser level which should really help.(plan to sell that after final grading and retaining wall install, if anyone interested) . another neighbor is letting me borrow his Kubota tractor for moving the extra soil, may take about 100 trips but i'm only moving it about 50 feet to hillside.
I have 6 weeks of 4 day w/e scheduled so hopefully by May we will have a pool...and getting ready for a great summer of swimming and hanging poolside with margaritas!!
thanks everyone for advice and pls keep it coming as I still need to research how to do the plumbing, electrical ( buddy is electrician and wired his own pool), install jets for cozycove, etc. anyone do there own conceete decking, I was thinking of exposed pea gravel aggragate for non slip factor)
pictures to follow, right now camera too muddy to take any pictures
