Somewhat related story follows:
My brother-in-law is a jack of all trades. Climbs mountains and is building a one man submarine (he was a submariner in the US Navy) and is one of the top abalone divers in northern California during abalone season.
He is retired and has sufficient time to pursue these 'hobbies'.
Their home is a big, three story place built in 1904 and is registered within the state as some form of historical 'artifact'.
He recently received a number of bids from licensed painting contractors .. Low bid at $18,000 and high bid at $22,000 pus a separate rental fee of $5,000 a month for the scaffolding.
So he decided to paint the house himself and purchased some scaffolding for $1,000 which will have to be taken down and reconstructed as he proceeds to paint which will cause him a lot of additional work but will save him $4,000 or more depending on the time it will take to paint the place. His paint estimate is $1,500.
Here's the test question for GetBiggers who like test questions:
If it would take two months for a pro to paint his house for a total of $20,000 plus two months of scaffolding rent, how much would he save by painting it himself?
PS ... He says that his color choice is "SUBMARINE GRAY". The present color is NAVY GREY.
I recommended OLIVE DRAB with a bit of camouflage thrown in.
But you civilians would not understand that.
