There is a fishing guide I know personally known locally as Fishy Rob, Robin Howard. He covers nearly all aspects of shore and estuary fishing and has recently taken to doing Fly Fishing too. Here is his website with more information. There is not much up on the Fly at the moment but it's all worth a look and he is a wonderful coach.

One of my mates that I go Carp fishing with has until recently fly fished all his life. He used to travel to Hampshire the majority of the time. I don't know tpoo much about it but I do know that it is incredibly expensive.
