Tincan-
That is a GREAT price for a re-wire. It sounds like you guys have a good method for doing the R&R. Having each tech have a specific task and area to work in is a smart, efficient way to do it.

I have restored and re-used original wire harnesses and I have installed brand new ones. Installing a brand new harness is my preferred method. Original harnesses can get brittle over time, and even with the best restoration methods and ohm checking after you're done, they can still have problems. The larger gauge power leads, like the ones tied to the ignition switch and at the fuse box, can be especially tricky because they rarely corrode and fail on the ends. The amp gauge wires are notorious for this. They like to corrode and fail in the middle of the harness. If you're lucky, it'll just cause an open circuit. If you're unlucky, it'll short out and the harness will burn and that can lead to a bunch of issues, none of them are good.

If you can afford to buy a new harness, it's the best way to go.
