Pool building time lines depend on a lot of factors. A pool can easily be completed in a 60-90 days if all your selections and decisions are made on the front end and your pool builder has his ducks in a row, gets all his subs scheduled properly and you don't have any city inspection issues. Most pool builders are familiar with the city codes, but always double check set backs and requirements yourself to save the hassle on the back end. Even with a ton of change orders, coordinating with our outdoor kitchen construction and delaying my pool builder a few weeks due to planned trips, he was able to dig out our old pool, fill in the back yard, and dig a new pool and complete in about 90 days, Also, weather can be an issue, so cross fingers for a dry spell.
As far as TV's go, you can get a cheap large- internet ready Samsung 4k from Target for around $500-$600. Buy a good TV cover that wraps around all sides from Amazon. I have two TVs outside that I keep covered, one is completely open to the elements for 6 years and I have no problems so far. I looked at outdoor TV's but figured I can by a new one every other year 5 times and still be better off.
