Another option would be to write the book self-publish and perhaps make even more. You say you have been publicizing yourself already and that's a big part of self-publishing.
It could work.
Erotica, Romance, Thrillers, Fantasy are really big right now in the self-pub world.
all of this of course is just my opinion.
