Man, what a bunch of whiners!
Even though the voting still has a long way to go, we have a pretty clear winner. And, YES that sign can be made and installed for less than a grand and YES, you could make money doing it if you're set up to make those types of signs.
My materials for the design being singled out could be a half sheet of 1/4" thick mill finish aluminum, digital prints, PT posts, hardware, paint and concrete. Assuming I use materials and processes like this on a regular basis, I would figure that the materials alone could retail for about $550.
I still have about $450 for labor, which would be worth about 5-6 hours of labor in a good shop. Knock off an hour for the design and I still have 4-5 hours to finish assemble and install the sign. So, how difficult is it to spray some paint, mount some prints and screw a few screws?
Not that I could or would work like this every day, or charge prices based on my costs alone, but it is possible to make signs like that, at that price and still make money.
One of the many issues about this approach is you'll burn out quick and there's a lot of potential for mistakes, which can cost you a lot more in the long run.
