Looking for volunteers

Looking for some chance/advice/volunteer:

I am really new to this group and working as a software engineer but I have been addicted into working some creative stuff as director. Currently I am taking some online course for video shot/editing and screenplay writing and working on my own music video project. I love documentary better and have some thoughts about this. Moreover, I really want to find some chance to closely join a professional movie project as a volunteer. Please feel free to message me if you have some thoughts and I appreciate any advice/opportunities!
