Nanny Needed For My Children - Full-time / Part-time

I havent started working as Im job searching. But, need child care for 2 little ones. Im looking for something affordable as I dont have a set job type or know how much Ill be paid. The last person to help us with childcare, a family emergency came up and couldnt help us any longer. She charged us according to what we could afford and I tried being as fair as I could to what I was paid as well as providing snacks and foods. She charged us 15-20 a day per child.
