Babysitter Needed - Full-time / Part-time

My Children are 4 and 3, Girl and Boy respectively. They love to play outside read the bible and watch some (very little) TV. I have them Every Other week so this would be a week on week off work. I wouldn't necessarily need help every single week that I have them but I do work out of town sometimes. I would need someone who is able to help with only a 24hr Notice (this is not a frequent occurrence). Would need to be able to pick up and drop off at school and pickup / drop off from other parent.
