Nanny Needed - Full-time / Part-time

Im a divorced dad looking for babysitter help for my two young kids when I visit them next weekend (5/9-5-10). One girl one boy but they get along great. Unfortunately, had some health issues where my left hand is not fully functional so I require help with some basic things when we go out on adventures(helping with diapers for the younger one car seat seats). Plus theyre pretty active so its nice to have another adult there to help. In all it would be about 10 to 11 hours across Saturday and Sunday morning.
