If what you're saying is the case, than Kickstarter is for the already successful not the "hoping to be" people.
Yes exactly.
Think about successful kickstarters. They either had a very cool prototype for some sort of gadget or had a massive following already, maybe both. Would you fund a guy you don't know that says he's great at something but has nothing to prove it? Its like a job interview, you have to pitch yourself. Why should these people give you their hard earned money? You need a reason to give people so they know you'll deliver if they chip in, and I'll tell you "I'm good at writing stories" won't work because that's objective and anyone can claim that without proof. Trying to sell a story is the hardest, because until you got it down for others to see, you have no idea if it'll be a hit with people or not, all you're selling is an idea. That's why most authors starting out need a back-up job.
No good at drawing? You said you're good at the characters, the plot, prove it and write. Or if you want to get good at drawing, draw the comic, no matter how crappy. Many webcomic artists who are great now, look at their first uploaded page and I can tell you it won't be as polished as their current stuff. Geez, the MSPA/Homstuck guy got famous by drawing heads on rectangles ( http://www.mspaintad...s/hs2/00001.gif ). Most fanart is better than his art and he's still got a huge following. It was the creative idea of the fans getting to choose the direction of the story that made it big.
Start off by doing it for free, prove you're worth funding, enjoy the creative process. Then you can do the kickstarter to fund the graphic novel. The same reasoning goes for getting an artist, prove your worth collaborating with by doing some stuff on your own first.
