Summer Time Baby Sitting Help Wanted!

Hello there our names our Jennifer and Clayton and we are the parents of two girls and one boy. Jacob is our boy who is 9 going on 10 years old and we have Scarlett and Marlee who are 5 and 6 years old. We are looking for some summertime help, the kids are not in school which is our normal go to, to help with child care while we both work full time. We are not looking to put kids in an after school program seeing as how we only need help with sitting for no more than three hours, one or two days a week. At this point we only need after school help with our son Jacob every Wednesday for the summer for 3 hours. Transportation from school to home is provided already. There is a possibility that in the near future we are looking to find a sitter for the girls once the school year starts, again for only 2-3 hours.
