Babysitter Needed For 1 Child In Richardson

Looking for after school care on the days I work (I am a Nurse and work 3 days per week). I usually only need 2 weekdays covered to pickup my son from school but would need 3 weekdays on the one week in my cycle (I rotate 4 week cycles). I typically work Su/M/Th but work M/W/Th once a month. I am not a fan of the after school program at my son's school and would like to get away from having him there if possible.
