Side scrolling 2D shoot em up in Unity

Hello looking for some help with a infinite 2d side scrolling shoot em up game. As of right now i just want to get a working prototype to give the audience a feeling of the game. I have done some work already. Looking for help implementing camera shake, waves of enemies at the right time, implementing bullet system health and score. That's really it. I have all character assets ill be using for the prototype. Looking for someone that'll be responsive and use they're expertise to clean things up make it more efficient. Thank you of course will be compensated
