30-45 second 2D Explainer Video with Simple animation for our mascot

We are a water delivery company who delivers just about anything that is drinking water, right to your door. We're wanting to make an animated explainer video that will introduce the pain points that come with picking up water from the store -> and then sensationalize the benefits that my water delivery company offers them -> our mascot will save the day. My guess is that it will take about 30-45 seconds to tell the story, so we'd like the script and storyboard to stay within that timeframe. We already have the mascot made on a .ai file, but we'd like to animate him so he can do some simple moves like talking, winking, flying, waving, and maybe some walking. We'd want our mascot to be part of the explainer video as the storyline ends with him saving the day with a convenient, hassle-free delivery of refreshing water! We will need a script, but we already have a base idea of what the video will consist of. Attached is a copy of our mascot. If you need more info, please feel free to ask anything! Thank you for your time.
