Reliable Babysitter required Knottingley (Knottingley)

I am looking for a babysitter for my two daughters for evenings from 6pm midnight on an ad hoc basis. I am an artist manager and run showcases for my singers and gig with them regularly mainly at weekends and some weekday evenings. I am looking for a reliable sitter who can entertain my 12 and 9 year old girls offer the supper and ensure they get to bed of time. We do get back late from most events. Often after midnight. I am prepared to pay the going rate to the suitable candidate.
