We are thinking of developing a project for YouTube with a few friends. We are open to any ideas, and does anyone happen to know about the points we need to pay attention to?
I think you can get in touch with Ruhi Çenet. I don’t know if you have ever come across him on YouTube, but if you look into it a bit, you will understand why I recommend him. I think someone who has brought a project like you want to life and has seen all the obstacles will be more useful to you than any of us 
I think he will reply immediately if you send an email; he is a sincere person. Good luck
