Babysitter Needed for my Children - Now Hiring

I have two boys, ages three and six. My oldest son is in school Monday-Friday, but my youngest is home with me full time. I'm a single mom, primarily working from home, but I need to start working in person a bit. I'm hoping to find someone who is able to spend 10-15 hours per week with my3-year-old. My schedule is flexible and I can choose which days I go into work. I'm hoping to find someone who is looking for consistent work with a really flexible schedule. Needs to be comfortable with pets, I have an indoor black lab. In addition to daytime childcare for my youngest, I am also looking for someone who can occasionally babysit weekends or evenings (both kids).
