Joanne, is looking for a baby sitter in Hurley

Hi there, I am sorry to message you and please forgive me if I am wasting your time but was hoping to be pointed in the right direction if you can't help me. We are going to a wedding on the 10th November in Hurley (and all based in London). There are 4 families who will be at the wedding with children and we were hoping to find 2 babysitters to look after our 8 children in total. Children are roughly aged: 3x 6 year olds, 2x 4 year olds, 3x 2.5 year olds and then 2 babies that will be with mums more than needing care (as tiny and still breastfeeding etc). We are needing a babysitter (or x2 babysitters -if you had a friend that could also come along) from 5pm to midnight and there are 2 rooms at the venue at the reception where the children will be based with travelcots, toys etc. Happy to pay £10-12 an hour per sitter. Any help / assistance would be most appreciated. Many thanks! Jo
