you might want to consider using kunaki
www.kunaki.com
kunaki is a fully automated cd manufacturer that allows you to upload your music and art files and then order as many (or as few) cd's as you want for a little more than a dollar a piece.
when i first saw it i thought it was too good to be true, but they're for real. the quality is not great, though. on-disc printing is a little weak, and some of the cd's i got from them skipped. and their software requires you to use a pc, which can be a pain. but for a short run in a pinch, they're a huge bargain.
