Can anyone recommend a golf coach in the South Essex/East London area?

It's also my first post after lurking for a while so its nice to be on board

I'm looking for a new golf coach, just someone who is easy to get along with and a good teacher from the ground up (I am a beginner)

I did have a good instructor but he was always trying to sell me something so it's put me off a bit. There are a lot of coaches in this area but I would like to go with someone who is recommended and a sound bloke.

Any help is appreciated.
