Part-time Day Time Sitter Needed For Infant In Orlando

We are looking for a great sitter for our 2-month-old son, W, in Orlando. We would prefer a sitter who has their own car, who does not smoke, who is comfortable with dogs (we have one friendly dog) and who is CPR certified. My husband works from home 3 days a week and I work from home full time, so we just need someone to come for days when he's in the office and I need help during calls or so I can get things done during the day. We're only looking for about 12 hours a week probably around 10 am-1 p.m. We would love to have a sitter for occasional evenings and weekends, but that's not the immediate priority. I know being a mothers helper can be intimidating, but I use to be a nanny and I hope to make our sitter as comfortable as possible! We are new parents and just need someone to be an extra set of hands.
