I second Pablo's advice to contact the smaller youtube, at least any work done you have a chance of self-promotion for yourself!
It's best to set up a Portfolio Page for yourself too if you haven't already, people like to view examples of work even if that's as little as a thumbnail picture, as long as you can prove your skills!
Hope you get to the goal you wish to get to! Message me if you need any help in the future i'm sure we can talk and see how to best benefit you.
