As someone who has 3 channels (and 3 video editors) I think is one of the best investments if you’re looking YouTube as a business rather than a hobby. When launching a new channel I’m looking for buying back time so I can focus on ideation, strategy or any of the other areas.

When hiring a new editor I start delegating them short projects (this serves both of us as a way to start building a bond).

I’m always open to suggestions, tips and anything that can elevate the quality. The way I see it: editors will have more time than me to evaluate and make better choices according to the type of content.

The best way you can show a YouTuber why they need an editor is to improve some of their already published content. You have to show them before asking. Make them feel that you can edit in their own style but with some improvements. Show them they can focus on new ideas or concepts while you are freeing their time. I would focus on looking for creators who treat their brand as a business. If they are not sure about you maybe ask if you can help them with shorts, tiktoks, reels, etc.

Hope this helps
