There was a woman in the Lewisham sort of area (can't remember exactly) who popped up on adultwork but kept deactivating, she's on my hot list but not displaying at the moment so I can't link you. She had quite a bit of positive feedback there, I think English and mid to late 20s. Not been to see her though, so don't have a review, but this might trigger the memory of someone who has who can point you in her direction.
