Hi, wondering if anyone can recommend an agency or a childcarer that might be able to help look after a few children at my friends sisters wedding? We are both nannies but based in London so don't know anyone in the area (near Leamington Spa). It would only be for around 90 min, supervising 3 children during the, and Tinies quoted £200. They are happy to pay well but that seems excessive to me! If anyone has any suggestions we would be most grateful! Thanks in advance.
