Babysitter Needed - Full-time / Part-time

For right now, Im looking for someone to babysit while my fiance and I go out on date nights, and possibly transition into long term help during the day while I work. I have a total of 5 children, but my older three are old enough to take care of themselves. Its mainly my younger two, who are 3 and 1. My 3-year-old has 7 of the top 9 food allergies, so we pay special attention to his meals and what hes exposed to.
