I have a bud, CurriePlays who Ive been watching for over a year now. He has great editing skills and makes awesome videos. He got an honorable mention in the description on pewdiepies last shout out video. Through that he gained 8k subscribers in a few hours, and he was also brought to the attention of Kwebblekop. When Kweb asked Currie if he wanted to edit for him, I think at first he said no, that he wanted to focus on making his content, so they did collabs. He played games with Kewb, Jelle, and Slogomanify and ut was great. Then he . finally made an agreement with Kweb, and he edits for him now. Finally, after about 3-4 years if hard . work, everything is paying off and he does YouTube for a living, editing for kewbblekop and making videos for himself.
What I'm trying to say here is that you should most certainly take ANY opportunity to take a hand up, but be smart about it. Currie was able to get a feel with working with Kwebblekop before he was assured that it was a good decision. I hope you have success with the videos that you're going to do with the larger youtuber, especially if they upload it to their channel and you do to yours too. I'd love to get opportunities such as this. But I don't have a computer lol.
Especially since these Youtubers were the ones that inspired you to start Youtubing. That in itself is something to be proud of
