Create an Character Animation

Hi everyone, I want to create a character animation. The purpose of the video is to show the benefits of using our company's product. Our product is an air filtering mesh to be easily installed at windows. First show the characters being uncomfortable and after installation of the product, they smile. The script starts like this. There is construction going on in neighbourhood. The construction created many dust. There are cars on the road and there are carbon emission from the car exhaust (dust). There are flowers and pollen. The dust and pollen enters into a building with people in it and a classroom of the school which is beside the building - split the video to building showing people and the school showing pupils in the classroom. The people in the house should be baby and elderly. The people and the pupils cough after breathing in the dust and pollen. Return the focus back to the house at the building. Show also mosquitoes and bees flying into the house and the mosquito stings the baby. Next, show the father bring the elderly and baby to a clinic to see doctor and look at high bills. After that, they go home and the father closes the window and switches on the air-con. The electricity bill comes and he sighs again because of high bills. Finally, he buys our company product and installs it at his house. The elderly and baby smile when they are at home. When electricity bill comes, the father smiles also. The above is the draft script.
