Excel / CSV File of companies and contact info

Hi, I would like to gather a list of gourmet snack companies in the United States. For each company, I would like the company name, company website, and contact email for the company. For the contact email I would like it to be a person who works at the company, like a marketing manager or advertising manager. If no person's email is available, any contact email for the company is good.

The types of companies are the following:
- at least 100 chips companies
- at least 100 popcorn companies
- at least 100 candy companies
