Sitter Job in Dallas, Texas

I am looking for a sitter for my son would is almost 3 and potty training. I am also 7 months pregnant , so someone with experience with newborns would be great as well. I start work on the 17th and for the first four weeks will be working from either 8am or 9am to 6pm. After the four weeks my schedule can be any day including weekends and the hours can range anywhere from 8am to 10pm. I cannot afford much right now, looking to pay $80-$100 a week or even less of course! Since I do not get paid til the last Friday of the month I would appreciate if you could wait to get paid, but if not then I can come up with money somehow. I need someone who is close to me or who can come to my place.
