Melissa looking for a babysitter or nanny in Halton Hills

Looking for help for a family whose mom has cancer and is currently in treatment. There are five kids but three are 16, 18 and 20 years old. We need help with the younger kids 8 and 11 yrs old, some cooking and light house cleaning. Looking for help between hours of 9-9. Perhaps live in. Some help for mom when her strength is low.
