Homebrew PCBs

OK, I'm not trying to go way off-topic here, but I don't know who else
to ask about this. I have a small board that I have designed (and built
many of by hand at home using TT) and I've had Olimex make several of
them. Now other people want to buy bare boards and build their own
boards. I have no interest in being a 'business' and selling these
things. Are there any companies or organizations out there that will
make and sell blank boards for your hobby circuit? I.e., I want to find
a company that will keep some small quantity of these boards in stock,
and have a web-store that people can buy single quantities from. Does
such a thing exist?

Thanks for any leads-
