Seeking regular after-school nanny/babysitter

[whywhy]

Hi, We are looking for regular childcare on Monday to Thursday evenings from about 4-8:30p, starting immediately. We are open to this being for the immediate or long term.

We are looking for help with everything from getting kids ready for bed to preparing school bags and dinner prep.

(Being new to the UK, I was unsure of the difference between a "nanny" and "sitter" so I wasn't sure which one we're after.)

Thanks!
