Are there any manufacturers that sell blanks with gold plated
connectors? Is that the best way to do it?

Are you going to use the PCI interface, or just steal power?

Why not put a PCI edge connector on the board itself ? That's what I'd do.
Don't forget how the plating's done. You need tiny fingers from each trace
that's a pad and they all need to be connected together. The board profiling
removes them.

For now, just steal the power.
But maybe put an i/f on later
Just buy a cheap PCI card.strip off the junk chips. Bolt on your pcb and
wire up power. That'as the prototype sorted.
A basic Google for "PCI prototype card" bought up stuff like this:

Cheap and easy to roll your own as well and get it custom
manufactured.

Onesies from makers like Vector are not cheap, but they do have a lot
of holes and support traces (gnd, supply) - all of which makes them
expensive.
Maybe pre-plan a "basic" layout and have a number of boards made -
then mask, etch and drill them for each particular use?

As others have suggested, there are development boards available.
IIRC, some are completly blank. Some are *expensive* though. You'll
have to buy one with the footprints you need, which may get quite
expensive, or not.

You'll likely have to decide that up front. I've seen some with
PCI->ISA bridges, which should make interfacing easier.
Well, this circuit is going to have to be redesigned for a number of
apps, so that may not be too bad.
Your favorite PCB design tool may have a symbol (and if it is good a stack
of VHDL for the interface logic too) already setup.
