Congrats and good luck. I know someone who makes about $30k a month on "erotic romance" and it's a volume business... crank and crank and crank and crank and crank and you, too, can quit your dayjob. I debated long and hard about whether to self-publish or jump into the arms of the traditional publishing model (a friend is a NYT best-selling author who offered to get me published - the first issue of Writer's Digest I ever bought had him on the cover) and decided that so long as it still exists, I might as well give it a go with the jurassic model. So now I'm waiting on his connections. SUGGESTION: Print that shit out. At least once. Just so you can see the damage you've done.
I've got about nine linear inches of shit I've written that nearly nobody has ever read, which is depressing... then I remember how much money I've made on six of those nine linear inches and I feel better.
