Role play dressing up clothes and props for 5/6 year olds (Prestwood HP16)

The local primary school class I help is giving a special presentation to the school on 'What I want to be when I grow up". We are looking for costumes and props for 5/6 year olds who want to be: doctors, nurses, airline pilots, vets, police officers, fire officers etc. Any spare bits and pieces you might have would be very welcome please - doesn't have to be a complete set of anything - even a single stethoscope, police helmet or airline pilot hat would be great! Many thanks in advance.
