Can anyone guide me to make a Extraction based FPS ?

Hello, my name is Abinash and am a 3D Animator, I know interface of Unreal Engine, but have no clue how to make games, and tutorials on youtube just show what to do, but they dont tell why they did that

I have this awesome game concept in my mind which I want to bring into reality, but need someone who can give me 1-2hr few times a week after work and guide me step by step on how to make games

I would be really grateful for that

Thanks
