There simply can’t be a guarantee. Even the Big Guys don’t give their audience any guarantees a series will continue past the first issue. How many times have you really gotten into a series only to see it cancelled? All too many times.
Yes, we could have run a kickstarter for a whole series, but would you really pledge to a comic from a publisher few outside the Northwest states of Oregon & Washington have even heard of? Personally, when I see a comic on Kickstarter asking for $30,000 my first thought is who the hell are they and are they certifiable? Raising, $6,000 to cover the costs of art is difficult enough!
