Any US fab houses with reasonable pricing 10-50 pcs?

There is a chance I need to order some PCBs but it's very soon going to be Chinese Spring Festival. The fab houses are on break until a week into February. Anyway, any USA fab houses that do reasonable pricing on 10-50 pcs 10cm*10cm boards? Thanks.

It could be a few times more expensive but can't be $25 each. I'm looking for less than $10 a piece and about a week of lead time and accepting Gerber files. Any pointers?

Liam's OSH Park is getting close:

About $18 for my board size but 12 calendar days. I'll take it as a backup option.

So maybe not so easy to find?! I'll use OSH Park then. Just read about sparkfun has sold its Batch PCB to OSH Park last year. When I last used the predecessor of OSH Park, only one person was managing the orders as a maker community thing.

Funny enough, I need 12 boards at 11.2 square inch each. So if I order them with the basic service, it's going to cost me $224. If I instead make it beyond 150 square inches for the cheaper service, I have to order multiples of 10, then my cost is still $224 but I get 20 boards (only really need 12 but nice to have backups). This seems cool coincidence!

FYI, the verdict:
Fab service: OSH Park
Board: 4"*2.8" = 11.2 square inches
Pcs: 20 (only needed 12)
Cost: $224 (of course)
Cost per board: $11.2 (closer to my $10 target than I expected)
Features: they do lead-free and gold finish. Also allows internal cutout (Don't remember if seeedstudio has allowed it these days or not).
Leadtime (<12 calendar days)

It's not US -based, but another Chinese option is Hackvana.
