DBChopper,
I'd definitely recommend Bristol Ground School for the exams. You'll have to do the specific helicopter ones more or less alone (unless that's changed since I did mine), but they are excellent otherwise.
What to do next? I wish I knew. Most of us in your kind of position gradually get to 300 rotary hours, then do an instructors course. Of course, that means the UK helo world is drowning in newish AFIs, with a shortage of QHIs. I did the R44 conversion... and haven't flown it since. I asked if it was worth doing a B206 conversion, and was told it wasn't really worth doing a conversion for its own sake; you can do it when you need it. I did a US quickie conversion anyway in California and flew 25 hours with the Traffic Watch guy on the B206 - great fun, good experience, but is it likely to make me employable? I doubt it. Of course, I haven't tried that hard for work. I do know one newish CPL who got some part time work - he knew the right people and was in the right place at the right time. You could do an instrument rating at a cost of £23,000 ( I think) and maybe (but only maybe) get a right hand seat on the North Sea. Or you could go abroad - probably the best option if you really want to fly helicopters for a living.
Sorry to be so negative - I'm not really because I've done the same thing and I think it's all been worth it - but that's how I see it.
Good luck (so long as you don't take my job anyway
)
