Need a friendly waitress for a small local event in UK

I'm hosting a private event at a rented venue in the UK and need a reliable server to help with guest service. The role involves taking beverage and light food orders, refilling drinks, clearing plates, and keeping the service area tidy. The event is casual, around 4 hours long, with approximately 40 guests. Experience with food safety and friendly, discreet service is a plus. I'll provide a brief on the menu and steps to follow, and there will be a short briefing before we start. Please bring your own black or dark-colored smart-casual attire and be comfortable standing for several hours. Location is accessible by public transport, and we can discuss stipend and breaks at hiring.
