Overnight Sitter Needed In East Falls, Philly For Tuesday Overnights - Urgent!!

I am starting a new job in which I work overnights so I need a sitter from 6:30pm-7:30 a.m. for Tuesday night into Wednesday morning. A usually has dinner around 7-8 p.m. and is asleep by 10 p.m. She is a very easy baby and usually sleeps through the night- waking up between 7-8 a.m. This would be a reoccurring position weekly until/if I can make other arrangements. For pay, I am willing to pay $20/hour while she is awake and $50 flat fee for the hours she sleeps. I have a guest bedroom in my apartment and you are welcome to sleep while she sleeps. I am a newly single mother with split custody and I have no family or friends in the area to help me during this transition.
