Looking for fortnightly cleaner for Hornsey, N8

Looking for a reliable, trustworthy cleaner that might be able to do 3-4 hours fornightly (in Hornsey N8 - near Hornsey High Street) and that doesn't charge more than £12/£13 per hour.

Do you know anyone that fits the bill that you can recommend? I'm probably asking too much, but thought I'd try.

Any suggestions gratefully received.
