Contact and Email Address Sourcing from 200 UK Companies

I have attached an excel document which lists 200 UK companies. For each of them I would like the details (name, job title and email address) of 3 key employees. Contact 1 must be either: Managing Director, Managing Partner, Chief Executive Officer (CEO) or Chief Executive Contact 2 must be either: Head of Human Resources (HR), Human Resources Director, Chief Human Resources Officer, Head of Personnel or Head of Employee Engagement Contact 3 must be either: Head of Marketing, Director of Marketing or Sales and Marketing Director All contacts MUST be based in the United Kingdom, and no generic company email addresses please (e.g. info (at)....) I have included a few examples in the spreadsheet to illustrate this, and I have also included the google hyperlinks I usually use to make searching for the emails easier. You may delete these or continue to use them as necessary. Once the email of one of the contacts has been found, the format should be the same for the other contacts, e.g. [login to view URL] (at) [login to view URL] , so it should be easier. You may use any websites necessary to find the data, but as a guide I would use: The Company website (given) LinkedIn UK [login to view URL] Google search (link in spreadsheet) [login to view URL] Any other appropriate Applicants should have experience in data sourcing. Access to existing databases would be beneficial. I am looking for a longer term partner and the work will eventually include company profiling etc. Thanks.
