Babysitter

I am in desperate a babysitter that I can rely on. I have been through several different sitters in the last few years and I just need somebody that can rely on. I can trust and isnt gonna quit on me after two weeks. I do have three children 10 seven and two they are amazing kids yes at times they have attitudes but what kids dont school is getting to start so I will need somebody to possibly help my oldest too with homework and stuff because it will be around the time they getout of school till I get off of work.
