Rachel, looking for a nanny in Liverpool

I need some help picking my 7 year old.son up from.school. I have 3 other sons of teenage years who make their own way home. He is on the pathway so I need him to be brought home until about 4.30/5. He is usually picked up from the school office at 2.50/3 to avoid the busy transition. Optional discussion on whether you need extra for my son in year 6 who’s pretty.much independent at home. Discussions around maybe a little bit of help with emptying school bags and making snacks helping me out round the house. However optional.
