The goblins in which they hire seem to be from the Venture Trading Company.
The company's name is a reference to the Hallmark greeting card company, which has a gold crown as its trademark, and sells holiday and special-occasion merchandise at its Gold Crown stores (including perfume and cologne). Valentine's Day, the real-world holiday which Love is in the Air is based on, is said by some to be a "Hallmark Holiday", that is, an event made up in order to sell greeting cards.
Judging from their company's name and speeches, they are most likely part of the Royal Apothecary Society.
