I'm afraid I cannot really help you but I know there is a multinational crowdfunding platform dedicated to game material (Guillaume Tavernier already did some crowdfunding campaigns there with a book that's been printed both in French and in English. Kickstarter would be a good option too (better than Amazon but I'm a ferociously anti-Amazon guy) but these options would mean you have to find a printer that'll respect your art. I've got some contacts here in France in publishing companies, if you have precise questions, I can try and get some answers for you this way. Partnership with a publishing company could also be an idea. Akae recently crowdfunded a game with a French company. Steffen Brand who works for Ulisses Spiele could be a good counsel too. My two cents.
