Cheap PCB prototpes?

So, 90 percent of the PCB traces are "irrelevant" never mind they
make for 90 percent of the circuitry..

90% of your traces are approaching 1m long? If so, you really need to
work on your layout skills. <good grief>

More than one company has been kicked off the approved source lists
for mucking with the process without approval. Maybe they'll learn.

Once a vendor who was allowed to finally make some boards for us, after
begging to show off their expertise and asking please, please please can
we do one of your boards: was allowed to make a small PCB that would be
used in a high voltage, high frequency situation. As they made the PCB
board and of course wishing to 'label' the board with THEIR logo, THEIR
address, THEIR part number found a large 'blank' area on the board to
leave all their information in nicely raised metal characters, cleanly
printed in that, convenient for them, 'unused' blank area. When they
delivered the blanks, I exploded at the salesman for putting metal in our
high voltage keepout section!

The salesman being fast told me we should have 'asked' [included in the
spec notes] that they not put anything there. The staring at him and cold
silence that followed resulted in profuse apologies and an offer to remake
the boards for no charge at premium speed. Too bad, they did nice work
otherwise.

Did you ask them why they bothered to etch the boards? You didn't
explicitly tell them that there should be no metal between traces. You
only specified where the traces were to be.

thanks! I needed a laugh this morning.
