New YouTube channel

Hello, I'm looking for help creating and editing videos for my new YouTube channel. The focus of the channel is to make videos about our new born daughter's atrocities and I need help from start to finish. I'm open to suggestions when it comes to creating a brand or aesthetic, as I don't have any specific guidelines in mind. I'm also looking for guidance on how to start and grow my channel so the videos reach as many viewers as possible. In short, I need help with creating, optimization, and promotion for my new channel.
