That's because the animation is very much the least important part of a successful show. It's the writing and voice acting. South Park is a great example of this. It's successful because it is funny and edgy. The animation could have gone a lot of different ways and had similar success I think.
I think fundraising is the hardest part of a project, especially for creatives. If a group of writers can wrangle some amateur voice actors to work, (Which I think would be the lowest paid actors) it should be easy to get a project up.
