I reckon you could do a 3 or 4 machine setup very cheaply - they don't need to be real fast PCs and you just need one fast central file store to download the pics to.
3x folding tables, 6x folding chairs, 3x cheap PCs, 1x server, 1x hub, 1x genny and the back of a tranny to put it all in. I reckon you could squeeze all that in under 1500 quid.
At £30 a CD that's not long before it pays for itself.
Obviously, I'll put this together for you for a very reasonable fee
