I don't live near you so I don't have an answer for a good preschool in your area. However, my husband and I both work out of the home and went through the whole logistical problem of preschool. The first year, my father in law would pick up my son and either watch him for the rest of the day or take him to the babysitters. It was a very tense situation so I decided that we could not continue that way. My son had met a friend at preschool and I would chat with the mother occassionally. We met at the park a few times during the summer and came to an agreement that this mom was willing to help transport my son to the babysitters. I would joke she was his taxi cab. I was very nervous because we had never let anyway else transport our children before, but it worked out fabulously. I decided to pay her because I did not want to feel that I was taking advantage of her. After all, I would never be able to return the favor. We paid her $10/day. It was a bit expensive, but worth every penny. I did not worry one bit (after the first week or two). I talked to this mom every few weeks and would ask my son, the preschool teacher and my babysitter how things were going. It worked out so well, that even though my son is done with preschool and her children is done with preschool, I believe she is going to help with my daughter's transportation next year.
Another thought is with the preschool itself. My son went to a preschool at a church and they had volunteers. One of the volunteers was my son's teacher's mother. They were available for arrangements. I never did this so I don't know what the deal was, but it is a thought.
