Babysitter Needed for my Children

We need an english speaking nanny for our 2 children in Key Biscayne - both toddlers. We're hoping to find the right fit for a long term position. Both kids are in pre-school in the mornings (except for days that the pre-school is closed) so primarily looking for care in the afternoons, but flexibility to cover mornings and evenings when required is a bonus. We have a dog (who is friendly), so must be comfortable with pets. Having a driving license would also be preferable.
