Research veterinary laboratory or clinics in Barcelona with appointments in spanish

Hi I need to do a research in the area of Barcelona to look for veterinary clinics or laboratories to offer them an innovative and disruptive fitoterapeutic remedy for all kind of animals and for most diseases, I will need to schedule with them appointments from September 5 onwards in Spanish language ( I speak english but here in Barcelona most do not) so they can receive me and I can give them a sample product with all the scientific specifications and testimonials.
