YouTube Creator Research and Data Collection

I run a video editing agency and Our ideal client is an established expert or coach who is already running a business outside of YouTube. Their primary pain point is a frustrating credibility gap: their video production quality is often basic or amateurish, which completely fails to reflect the high value of the services they offer. Because of this, they deeply value cinematic quality and powerful storytelling, viewing it not as an expense, but as a crucial investment to build brand prestige and justify their premium pricing. They aren't looking for a simple freelancer; they're actively seeking a professional production partner who understands their business goals and can translate their expertise into visually authoritative content. Ultimately, their goal is to build a reputation as the undisputed standard of excellence in their niche.

I need someone who can find such creators on YouTube and extract their email's for marketing purpose and properly structure it in proper excel with name , channel name , link and niche .
Do you think you will be able to find such channels and collect their details ?
