HI Layla - my advice would be to get onto this ASAP - its a bit tricky to get in with your preference, so you might need to ring around.
I can strongly recommend the Midwives Collective - they are based in Balmoral, and are a really neat group of women. You will get a specific LMC - but there are great back ups. There number is 815 8108. I used Stephanie Vague.
I can also recommend Lee Moselen - she is based in Epsom, and although I didnt use her (I know her through family - so it didnt "feel" right to use her). I have heard FANTASTIC things about her as a midwife.
Good Luck!
