Source Directors/Emails and enter into Excel

I am looking for someone to assist me in finding names and valid email addresses of current company Directors, preferably Finance Directors.

There are 3,446 company names in the attached document. If you are happy to help, please work on a few companies to get an idea of how long it may take you to find names for all companies.

If you cannot find a Finance Director: a Chief Financial Officer, Managing Director or Technical Director would be helpful.

Through my own experience, I have found that LinkedIn is a helpful tool.

Thank you for your time, I look forward to hearing from you.
