Nanny Needed

We are looking to build a relationship with a local babysitter for occasional/semi regular babysitting looking after our two girls when we have occasional work schedule conflicts / for date nights etc. We also have a specific work schedule conflict coming up on 6th October where we would need someone to watch the girls from 4-11pm, so we would also ideally like to do a short test run babysitting on an evening before that for a couple hours if possible, to ensure the 6th goes well. We can be flexible on date/time if the extra date.
