Babysitter wanted for childcare in Barcelona

We are a family of 3. We are originally from USA but have lived in Europe for 12 years with last 3 years, here in Barcelona. Our daughter is 5 yr old and goes to St Peters international school. She is energetic, initially shy but usually chatty and fun loving. She likes to be outside in the park most of the time and other times, build legos and other things at home. We need help with after school and baby sitting for when we go out for dinner. The usual schedule is:
M to Th - 5 to 8 pm
F - 3:30 to 7 pm
One weeknight, stay late till 10 or 10:30 pm - pre-arranged
One weekend afternoon - 4 to 7 - pre-arranged The primary responsibilities are to play with our daughter, take her to after-school programs (if we enroll her), cook her something simple for dinner and shower her before bed.
