Hi,http://www.seeedstudio.com/depot/fusion ... Path=64_12
Basically you send them the pcb files and you order a few pcbs at cheap prices. They will keep the design on file and let others order the same pcb directly from them. Max is 10cm x 10cm for that type of stuff, I am not sure if it will work for FreeEMS.
"The initiator make a board (maybe own design or any work under open source license), get 5 pieces PCB for just $30, we share the manufacturing costs and produce extra. The extra PCB will be stock by us and listed on a very affortable price like 5-8$ with minimal shipping cost. (About 2-3$ flat rate). You may share the $30 with other people, end up getting an industrial standard one for less than 10$."
* FR-4 material 0.4-1.8mm thickness

* 1oz Copper
* No limit on the number of vias
* No limit on pads or components
* Color: Green
* 100% E-test
* Only one design per serivce."
Their specs are very good for prototyping and pricing is the best I have come across. Price is not so good for large volume.
