  There's a company up the road from me here in Phoenix, AZ, USA, called
Avanti (see their web page at: http://www.avantiweb.com/).  They do
beautiful work, but their pricing reflects this.  I can't recommend them for
prototyping jobs.  But, it doesn't cost anything to ask for a quote.  So, I
suggest adding them to your "Request For Quotation" list.  Get all of your
ducks in a row, and then enter the final specification of your board into
the "form" on their web page.

  Do this for lots of companies and go with the one that makes you feel the
most comfortable.

P.S.  The reference to Yahoo was of great service to me.  I found a couple
of places I had not heard of before.  For example, EP Circuits
(http://www.uniserve.com/epcircuits/) offers 36 hour turnaround time for a
double-sided board for $0.50 per square inch and a $40.00 setup fee.  You
can e-mail them with an attached ZIP file containing the Gerber photoplot
file and the Excellon Drilling file plus your name and address and Visa card
number.  And, three days later...  Yahoo!

  I mentioned Avanti because they do good work.  But, you have to negotiate
the price.  And, you have to know what you want to pay, first.
