One i've had luck with is posting on Craigslist and putting ads in local
newspapers to where the manufacturing was done. Use to work better when
people read newspapers, but even last year I got an e-mail back from an
advertisement in a paper with an offer of just pay the media mail rate for
a full bankers box of docs.
