promote video's

I'm looking for someone to help promote my videos across multiple platforms to help boost my visibility and subscriber count. We've identified YouTube as the primary platform with the goal of gaining subscribers. The target audience for this promotion should be everyone, so we need to create meaningful and interesting content that will drive engagement. We need someone who can create an effective strategy and then execute it - from designing captivating images and drafting relevant descriptions to researching related topics and understanding best practices for promotion.
