List of Nutrition Powder Brands

I am looking for a freelancer to create a list of Nutrition Powder Brands. The list should focus on Protein Powders and be targeted towards health-conscious consumers. I would like a CSV / excel file of a list of up to 5,000 Nutrition Powder Companies and their emails. Rather than a generic company email, it would be ideal to have an email of a contact at the company, for example, the CEO or Head of Marketing. Ideally a three column sheet with company name, company contact email, company website.
