Hi Loudoun,
I'd echo Indetrees post; go for it. The industry goes up and down and there's frequently a need for low hour pilots to fill left hand seats on the North Sea.
Go into it with your eyes wide open though. If you go offshore you'll need an IR which will take the total cost of training to near £100,000 rather than the £50k you've seen advertised. The training is hard and time consuming and many fall by the wayside during the journey.
But on a positive note....best job in the world. Good luck!
