I'm starting one of my biggest projects yet, its a game about dealing with depression. I want this game to be as professional as possible, which means i need people who are experienced with the following

-Understanding Script
-Good at map creating
-And people who are able to contribute their time into adding to it whenever I am not around.

I know its a lot but I would appreciate it if people would help me out. More details on what I need done if you contact me directly
