In home sitter for 3 amazing kids! - Full-time / Part-time

I am a single mother of 3 children, 2 boys and a girl. My sons are both high functioning autistic. I’m looking for someone who could come to my home and care for my children while I am at work. I am a home health aide and care for a client here in Tiffin from 9-3. Right now I work the hours as to be able to be home for my kids before and after school. My youngest is being cared for by his grandmother but I need someone else to relieve her of this responsibility. I have my oldest 2 children every other week.
