Change the words to suit whichever place or thing you are tendering, seems to be the FS business model:
One contractor was from New York, another from Missouri, and the third from Florida. At the end of the tour, the guard asked them what they did for a living.
When they each replied that they were contractors the guard said,
"Hey, we need one of the rear fences redone. Why don't you guys look at it and give me a bid?"
So to the back fence they went. First up was the Florida contractor.
He took out his tape measure and pencil, did some measuring and said, "Well I figure the job will run about $900. $400 for materials, $400 for my crew, and $100 profit for me."
Next was the Missouri contractor. He also took out his tape measure and pencil, did some quick figuring and said, "Looks like I can do this job for $700. $300 for materials, $300 for my crew, and $100 profit for me."
Then the guard asks the New York contractor how much. Without so much as moving the contractor says, $2700."
The guard, incredulous, looks at him and says, "You didn't even measure like the other guys! How did you come up with such a high figure?"
"Easy," says the contractor from New York, "$1,000 for me, $1,000 for you, and we hire the guy from Missouri."
