I'm interested to know where these estimates come from. You can get PCBs for much cheaper in Shenzhen.

Source : A rough quote from http://www.sz-jlc.com/ came out to $0.15 for less than 10k boards

Shenzen pricing, 6 layer board with 8 mils holes, and 4 mil clearance. ENIG finish. 2.3"x3.3"

Looking at the picture of their board the package is most likely 0.65 or -- possibly 0.4 -- pitch which means much laser drilled holes.
