Assistance required with job hunt (recruitment help)

I am hoping to find someone who can assist with my Cient's job hunt for a Google PPC Executive entry role in London. We have put together an excellent CV and cover letter. I am looking for someone who can compile a comprehensive spreadsheet of a list of 85 or more potential employers (all top Digital Agency - head offices) the names and email addresses of the relevant people to target in these companies, i.e. head of recruitment and head of Google adwords PPC department.) Please demonstrate your recruitment research skills when responding, or anything else you can offer in the hunt. Many thanks Dvonne
