If you only have 1 video and 10 subscribers; why would I want to collaborate with you? I've been doing this for 2 years - no shout outs, no handouts - posting one video (if not more) a week for 1.5 years - with a lot of blood sweat and tears. As the market gets more crowded - it's a good and bad thing - but putting in the work shows that you take it seriously (even as a hobbyist). 

If I'm not able to relate, see the artistic value, or any sort of value - I am not going to collaborate with someone just for the sake of collaborating. Instead of focusing on collaborating - focus on your videos, production value, camera presence, and constant improvement. 

Your last post was three months ago - where'd you go? Or.. you post videos consistency but I don't really see much of an improvement. It's a double edged sword. I sometimes catch myself getting to comfy with my content but then once I realize it's not enjoyable anymore for content wise - I throw a curve ball - whether that's incorporating more cinematic cuts, or completely changing topics. 

If you understand these three overarching factors and apply them to YouTube - you're good to go. By the way, I don't try to paint myself as this condescending person who posts videos on YouTube - but the truth is a lot of people who say they 'do' YouTube - it's just average - and average doesn't get you anywhere (there's exceptions but that's another story..) - you want to be good. If a person has 10 subscribers but their content is golden - I would check out their stuff - there's exceptions.

Conclusion, put in work - YouTube is a lot harder now - I'm still in the trenches trying to figure it out but I'm not going anywhere; and if you want to come play - you better play. I still remember when I barely hit 50-100 subscribers - I e-mailed people that I looked up to being so excited to work with them but to only find out I get the silent slap in the face of 'no reply' but truth be told - put in the work - and you won't have to introduce yourself.
