Create a Google Extension 'Baseball Game' that tracks statistics (from coach/scorekeeper perspective) for Recruiting Industry

I want to create a google extension that is a baseball game from the perspective of the coach/scorekeeper who is tracking statistics - but very simple, kind of like a home run derby style. It will eventually be converted into a business tracking tool with game-ification for sales/recruiters and sales managers/recruiting managers in the sales/recruiting industry. There are a lot of parallels between sales/recruiting and baseball so I'd like to make the job fun with this type of game. All animations will be triggered by manual inputs selected by the user that can be tracked by the user. The user, acting as the coach/scorekeeper will manage and count the following stats: Swing and a Miss (Strike) Swing and a Foul Ball Hit: Single Hit: Double Hit: Triple Hit: Home Run Based on whether these stats "+1" or "-1" certain animation events will change what is happening on the baseball diamond UI. I've created an interactive mockup of what this will evolve into which I can share to show more. Ultimately, I need someone to help me build everything, the backend logic and the front end animations but there won't be any user controlling the graphics as everything will be triggered by whether the user updates manually whether they did any of the following actions. I have attached the pictures of the users already to help you understand the look and feel of the extension app.
