Babysitter

I just arrived from the United States with my two girls (ages 5 and 7). We all speak *some* Spanish. I am hoping to find someone who can pick up the girls from school (Santamarca) at 5pm and watch them for a couple hours. Preferably 5-7pm, three or four days a week. Get them started on homework, give them a snack, perhaps help get dinner ready for the girls. Some English is helpful but need not be fluent! We all want to learn Spanish. Chamartin/Prosperidad area.
