Animation and cartoons?

Hi... I was hoping someone might be able to help send me in the right direction. I wanted to start a blog character that would do the news and comment.

Here's the thing... I am a pretty good cartoonist, but all I want to do is draw my character once. A chipmunk sitting at a news desk like the typical nightly news. On the upper right hand corner would be a small space to put AP news photos. The photos and the topic will be real, but the rest will be cartoon.

All I want to do is have to draw the cartoon once. A chipmunk at a desk. Then daily (or weekly), I would add my own voice, speed it up, and add the AP photos that would go with the story. The bottom line would be an angry conservative chipmunk who does the news (along with his own commentary).

I want it to be funny, informative, and entertaining - as well as politically incorrect.

Does anyone know of a program or something in which I can have this done? So all I have to do is add the sound and photos?
