I would rather have that swapped out with plexi from tap plastics or a place like that. 

The duration shingles typically have a plastic nailing strip that is nice for an installer and good for the life of the shingle.

I can write and publish an article tomorrow about how to do heart surgery but that doesn't mean I actually know how to (I don't).I think you'll find that most service professionals catering to the real estate industry have moved away from hourly billing.

I put the home depot plastic mini-blinds so there is at least something.

Trust me, anything plastic will be your "gold" and for more ugly it can look, you will love it on the long run!  

The 2nd contractor I had looked at it is now out of the picture as he just lost his right hand man due to emergency surgery that will put him out for 10 weeks.

If you buy a Moen faucet at HomeDepot its feather light and made entirly out of plastic; you can get the exact same Moen at a plumbing supply house made of metal.I am usually over $3 per SF for top quality material.

@John Teachout, last summer a neighbor and I, remodeling separate bathrooms, successfully stacked two wax rings -- one with the plastic insert and another without -- when reinstalling toilets that had been on sheet vinyl and are now on tile. 

So many, where to start....The most recent(about two years ago) had plastic tub half filled with cat poop...yeah about 30-40 pounds of cat poop...scooped it right out of the litter box and into this tub, she just never emptied this tub.

If there's any question, I would wash it, seal it, cover it with 6 mil plastic and then go down with the new carpet and padding.Spraying/drying does not "remove" anything.
