need a seo for YouTube Chanel

I'm looking for professional SEO service for my existing YouTube Channel. Specifically, I need keyword optimization to help get better ranking in search engine results, as well as channel and video optimization. I have my own existing channel content and video material that doesn't need additional written content, so I won't be outsourcing any of that. I'm looking for someone with expertise who can help optimize my current channel and videos to improve my search engine rankings.
