Chiara, offer part-time childcare in Gotherington

My name is Chiara, I'm Italian and moved to Cheltenham in 2015 with my husband and our 2 children (aged 8 and 4) to start a new job. We live in Bishops Cleeve. We also have a dog, a 13-years old golden retriever.
I work full time 9-5.30 and my husband works 4 or 5 days during the week till late. I'm looking for a nanny to take care of my children from 3.15pm till 6pm during the week. Days change depending on my husband shifts so it can be for 4 or 5 weekdays. Unfortunately, I can only give a week notice for the exact days. I would need someone that can collect them from nursery (Mary P'S) and school (Bishops Primary Academy) and bring them back home. Thanks!
