Babysitter Needed for my Children - Full-time / Part-time

I am looking for a great trustworthy babysitter who can take care of my kids when I have to travel out of town for business purposes as a solo parent of two young ones (8 & 11). Trips coming up in August and September. I would prefer someone who could help out with homework, getting them to and from school, meals and staying with them overnight while I am away. I would prefer a babysitter who has their own car, who does not smoke, who is comfortable with pets, who is CPR certified and who has college degree.
