Babysitter Needed for my Children - Now Hiring

I may be taking a new job that requires me to travel for work once a month. Some trips will be same day, I will leave 5 a.m. and home at night. The kids are one in high school who take bus and one in elementary school who is driven. need someone here overnight with them. they do taekwondo and tutoring as well. It would also be helpful to have transport to those events if I had to travel for work.
