Mobile Game Optimiser in Unity

I'm making a Tank Multiplayer game on Unity and wanted a level Optimiser for the game. My first scene is a simple scene with tanks and a garage but FPS is low (3-6 FPS). Task#1: Scene unoptimised and you need to Optimise it using assets like Bakery and Mesh Baker, which is already included in project and keep the look of the scene as it is in real-time lightning. You also need to decrease the loading time of the game from 20 secs to 4-5 secs (Discuss in DM). Will pay you INR 1500, total (3500) for the first task and subsequent money for other work. As always, DM me for more info.
