Where can a 19 year old rent a car in Northern Ireland? - northern ireland car restoration companies

I'm hiring a student from 19 states and the need for a car in Northern Ireland in preference to Belfast City Airport to collect. If I could get insurance, it would be a perfect location. Where can I rent from? Many seem to have a minimum age of 21 years. Thank you!
