Find Emails from List of Companies

I have a list of companies that I need help with finding emails for from specific roles within the companies. This list of companies was provided to me from my own resources, so no need to generate one. The emails need to be from specific roles within the companies, so I need someone that has experience in finding that information. I'm starting with a trial sample, and following up with a subsequent task afterwards.
