Looking for English (from UK) Private Teacher (Santiago de Chile)

Hello,
My wife is from Venezuela. We are living here in Santiago (San Carlos de Apoquindo). We need to find a private instructor urgently for up to 20 hours/week. In our house won't work because our 3 year old daughter would interrupt too frequently.

For reasons we can explain later, it is critical that it be a native-British speaker. We could commit to 2 months or so if we agree on a price per week.
