As an American currently working in Madrid, I'd be able to easily research media monitoring agencies for you -- both major agencies and smaller, independent ones -- as well as inquire about the presence of an English-speaking employee that could assist you at each organization. Since only certain employees, if any, would be able to communicate with you at any given agency, I could provide you the contact information of those particular individuals and if requested, speak with them in Spanish first to ensure that this agency/this employee would indeed be able to provide you with the assistance you need.
