Babysitter Needed

We have a 15-year-old and a 12-year-old and need coverage in the afternoon to drive them to various local activities. It may be from our house to the activity or picking them up at school and bringing them to the activity and then home after the activity. We would need someone from around 2-2:30 to around 5:30. We have a wheaton terrier (about 30 pounds) dog who is extremely friendly and loves everyone. She knows to stand by the back door which she needs to go out and and backyard is fully fenced in so there is no issue letting her out back.
