Sitter Job in Newark, New Jersey

I'm a 22 year old single mother of a wonderful 1 year old. I can't do much like work or do things because its so hard to find a good reliable person that can watch him for me. I need a sitter for the weekend sometimes and a few days out the week. I go to class from 5-8 mon-thursday so I would need a sitter at least 3 days out week because my grandma helps me out also just not enough like I need. I just expect someone to be excellent with kids,clean, have good intentions and trustworthy my son is my world.
