Filter a CSV file -- 2

The supplied CSV file is an export of all my Linkedin contacts. I need to have a list with only these contacts who are responsible for communications, public relations, public affairs, social media or digital communications. So everyone with titles like "Public Relations Manager", "Communications Manager", "Communications Director", "Social Media Manager", "Digital Officer", "Head of Marketing", "Marketing Manager", "Head of Communications", "Reputation Manager" "Media Relations Manager" etc... need to be filtered out of the list and saved in a new file. These filtered contact will have to be organised in a new list and saved as a tab delimited file or CSV. The information will have to have this order: email address, first name, last name, organisation, country, title (if this information is available of course).
