I need a video game programmer

I'm using Unity and the Corgi Engine which is written in C#. [login to view URL] I've managed to get this far without any programming but that time is coming to an end. Upon moving forward I will have to purchase a copy of the Corgi Engine for the programmer. I'll be looking for about 7-10 scripts for abilities. Some of what I'm going to ask is already an option, but I don't know how to extend that, or whatever you call it. Also, my levels are heavy, poorly optimized and in need of help. I can provide a Steam Key to the programmer to get an idea of where I'm at. Thanks for your time.
