- it's been a long while since I've been in the game so I've no recommendations, but Google "CD duplication" and you'll have plenty of options
- costwise expect 30-80p depending on where you go, the print run and packaging style.
- printing takes longer than CD pressing, get the cover designed first!
- Expect a turnaround time of up to 3 weeks, but you might find someone who's having a quiet spell and will be quicker... specify what you need when you're asking for a quote.
- And pull in some favours: do you know a designer who'll do the sleeve for free? Or hold a competition at the local art school.
- don't make too many, it's better to run out of a "limited edition" than be tripping over (paid for) leftover copies in your garage for the next 10 years (like a mate of mine did!) And/or get the bands to commit to buying any leftovers from you at cost.
- unless the charity part of the gig might object, try and find a sponsor: a recording studio, a venue, local radio, maybe even the duplicators? It's only a few hundred quid to them, but you might cover some/all of your outgoings.

Good luck!

.. the sponsor deal was on my mind. I can afford to do a run of a few hundred but as I've got boxes of books I published for Kevin Coyne just as he died I'm thinking of how to spread the cost so I don't have to rely on the bands to commit to the leftovers. One thought I had was a run of say 500 allocating 100 to each band and 100 to me for direct sales. Then to give each band 20 CD's for free to sell and then for them to use for subsequent purchases at cost. But that then that means them selling the first lot and ordering the next - a sponsor would cut that loophole out.
Ideally any deal struck would finance furture releases.

Tony, any chance you could provide a link - or some details - relating to this fringe Festival? I only ask because my lad has just set up a website covering gigs and bands in the Leeds-Sheffield-Manchester triangle and this is probably the sort of thing he'd be interested in covering.

Cheers
