Babysitter Needed - Full-time / Part-time

We are looking for a reliable afternoon babysitter for 2 children (ages 10 and 7) in Minneapolis/Saint Paul (we are moving from overseas and will be staying in Minneapolis for first few weeks, then moving to Saint Paul). Sitter will need to pick the kids up from school for the first few weeks (then bus stop), make snacks, and help with homework. We would prefer a sitter who does not smoke and who is comfortable with pets.
