Promotional model for luxury watch brand launch event

A Swiss luxury watch brand is hosting a three-day private exhibition and press launch at a central London venue. Looking for two promotional models to host guests, guide press through the product range, and represent the brand at evening events. Formal presentation experience preferred; smart English essential; confident in a high-end client environment. Wardrobe provided by the brand. Event runs across Thursday to Saturday; model attendance required all three evenings plus one afternoon setup session.
