One mate used these folk to print his book (Echos of a dream, a crag rats tale by Alan Richard McHardy)
He had a type setter called Monkey gone to Heaven but I can't find them online. There will be others. He printed as many as he though he would sell and made money on each one.
Another mate got a publisher deal and all the marketing etc that goes with it but he only gets about £2 a book from them. In Some Lost Place by Sandy Allan. Published by Vertebrate Publishing but it's hard to get a decent deal with a publisher. Self printing seems the best option.
