Need a friendly waiter/waitress for small family event

I’m hosting a small family gathering and need a reliable server to handle drinks and light food service. The event will be indoors at my home in the UK, about 20 guests. I’d like someone with good people skills, neat appearance, and previous catering or restaurant experience. Tasks include setting up a drinks station, serving appetizers, clearing plates, and ensuring guests are comfortable. Access to the venue is easy, and I can provide all supplies. The shift is for the afternoon, and I’d prefer a punctual, professional person who can start on time and stay until the end. First aid knowledge is a plus but not required.
