we were looking to get our mixtape manufactured last fall and this was the advice we got:
None of them will do it officially. You may be able to slide it in under their nose, but you also run the risk of sending them your money and them saying nope we can't give these CDs to you, and we can't give you the money back b/c we already manufactured them.
Pretty much unless you can prove you got clearances, your up shits creek as far as getting them manufactured. None of the manufacturers are gonna knowingly take that risk, because if the hammer comes down from whoever owns the publishing/sound recording rights, they're liable right along with you.
What you should do is find the cats in your area that everybody goes to to have their mixtapes duplicated. It'll probably even be cheaper. They'll be burnt, not manufactured, but you can still get text on the CD, and probably even pictures. In DC, we got a connect to get 1000 CDs and cases for $650. The inserts are a separate matter.
