Get the MSDS sheet for gaseous and aerosol
copper and various oxides of copper before recommending that. You can
outsource the work to some sign-makers though, who have plasma cutters.
As far as accuracy is concerned, sawing is
just fine, and as accurate as the equipment you use. Do rough cuts how
you want, and finish on a table saw with a fence. (and proper blades).
Oh, yeah, regarding sawing, copper dust is
poisonous, too. As is liquid ferric chloride with copper guk in it.
And the fumes from it. Probably won’t kill you your first time out,
or your 1000th. But wear gloves and a mask anyway.
But try the $22.00 solution first.
After you decide to never do that to yourself again, have your metalshop shear
it for you.

OK Mark, Sure, but the
difference in cost is enormous and mechanisation in the form of bandsaw or
jigsaw is not as accurate as a draw tool used manually.
Any more suggestions from anyone in an inventive frame of mind?
This could be a real big issue.
