Create 5-10s simple cartoon animation in black and white

I would like to create a cute 5-10s video "intro" of a simple cartoon character holding a video camera and doing something active. Maybe putting a camera on a tripod for example. I am thinking of a level of simplicity like Leunig cartoons, although I am not saying "make it look like Leunig". Just that level of simplicity. I want to have a file in a mp4 or quicktime format that I can use as the intro to a variety of videos. (videos relate to tips on video production ie lighting etc). It may be that over time we develop this character, and create additional small clips as custom introductions for each video that we do... ie one for setting up lights and in the 5 second animation we have the character turn on a light. I see the finished result being used in the middle of the video screen... occupying only perhaps 1/4 of the height. So, mostly white space around him. I also need to create a matching "outro" of equal length, If you have questions, drop me a note.
