Maybe you should split it into thirds... cut the funding level to something more manageable, say $1,500, for a 22 page booklet? Then you can do a trilogy (or more, if you're so inclined). I wonder if maybe people aren't supporting it at a $3,500 level because you don't have much history publishing. Also there's definitely a gamesmanship sort of deal with these crowdfundings, people like to contribute to stuff that's going to "win" and has momentum.
Don't give up! I want a PDF, at least.
