IC Fabrication Company...

There are places in the U.S. that can make PCBs for much less than that.

I've not been able to find one. In most cases, there is a setup charge that makes small lots uneconomical.
Places I have tried were not able to accomodate combining small boards into a panel for unique users.
I suppose if you wanted to take on that task, as dorkbot/patchpcb has done, and with a US manufacturer, you might make a go of it.
