boards and components and assemble them into a product for you?
If you're talking about the PCBs, then my company ("Hackvana") can
supply you 10 PCBs for as little as USD19 including shipping.
Here's my guide:

Here's a picture of some boards I supplied recently:

There are also several other suppliers you can use. Everyone has

PCBs. For PCBA that's a really important point. Sometimes it's done
by you purchasing the parts and sending them to the assembler.I have lived for several years in Shenzhen China, electronics

manufacturing capital of the world, and that's a big issue. Part of
the problem is that parts (especially semis) that we in the West think
of as common and garden-variety are sometimes not that common in
China, and vice versa. The two sides of the Pacific have different
ideas of what a standard part is. Generally what people do is hire
someone to do their part sourcing in China. Also, you always want to
make a small number of prototypes using exactly the same boards and
parts as you intend to use when you go for production.

Yeah sure, except for the confusion w/ PCB vs PCBA.
My regards, hope this helps!
