Burning your own CD's is easy - making professional (ie permanet ink) labels and J cards is a bit nmore tricky. Anyone can do the art work but it takes someone who has done it a lot to avoid the worst mistakes and still make it interesting. The thing about doing some of it yourself is pay as you go.
About 4 years ago an early English band told me they paid less than £1 (each) for a single batch of 3000 labelled CD's, Jewel Case J cards and I think that included the artwork. And they sold them inside of a year at £12 each at gigs.
How cheap is a run like that now?
