Hey Bravo 99,
my understanding of the way CHC and Bristow operate is that all recruitment goes through Aberdeen and that nothing can be agreed at the local bases.
I could be wrong though ! have you been up to aberdeen to see all the companies as that seems to be the way that people get their names nearer the top of the list ?
I am suprised that instructing jobs are so hard to come by, when I got my instructor ticket in the late 90's there were 10 unemployed instructors on every street corner (well almost) and anecdotally I had heard it was much better now, but this is the time of year to get work, if you are mobile I am sure you will get work this summer of some sort.
good luck
CF
