Script writing for a promotional video (humor involved)

Hello, I have a small life insurance agency where I would like to create a series of videos with a storyline. I'm thinking of a soap opera or something along those lines. My idea is to create a family with complicated issues and on the script interject how they did or did not have life insurance and how it impacted their lives. I have an ant as a mascot that I would like to use as the narrator of the events. I want to promote it in youtube, my website and wherever possible. '
I would like the script to be so catchy that people are looking forward to the next episode. I will be using cartoons animations as the characters. Some episodes might have three characters others might have 5...etc
I want them to be short but entertaining. Anyone interested?
