Also, i looked and most indie comics aren't even consistent. They might get 20k+, but only for a single issue and then drop like a rock. Series like Walking Dead, TMNT, Bone, Scud, etc sold poorly at first, but they took off and kept solid numbers throughtout their run.
This is why they get shit made outside of comics: toys, video games, movies, cartoons, etc.
