Eventing stable that does lessons?

[Desperate2012]

Hi, I'm in my 30s but been riding since... Well forever! I've just had a baby (9mos old) and am ready to start riding again. I rode up to 7mos pregnant, so it hasn't been long really, and in the past I've evented to Novice (in my early 20s), hunted, etc etc. however, before my pregnancy I was sharing and schooling horses 2-3 day per week and don't want that commitment with a baby (yet!).

I'm looking for somewhere, preferably an eventing yard, that does lessons at a fairly high calibre to start back again. Im happy to ride young horses and/or school masters, group or private lessons. It could be a schooling opportunity for eventer with a few horses too. Any suggestions? I live in South West London, so Surrey is ideal and not sure how much further I could go.
