I need a Programmer

I am Philip and be working on my finnished college project as a real game project. I can't get a few things done myself where I really gladly would love to have help with. Making Login and Register system for having accounts. Having a smooth and living AI system for Co-op gameplay Having a few more rounds settedup. Finding and fixing bugs I dont see. and Getting rid of my old weapon system and implementing a new fully responsable weapon system for movements, covering, aiming, shooting and reloading using a Unity asset or fixing up all bugs in my own created system and get it run smooth and look well. The project has been done in Unity and has a size of 7.2gb. I don't got a wide budget as I haven't been able to work due my handicap and because it was first a project for school what I now really wanna continue.
