I heard from an unsuccessful applicant that CHC are looking for 1000+ hours at this stage, leaving perhaps Bond for fresh CPL IR's in Aberdeen? It could of course all change if they don't find the numbers. Unfortunately this is the danger or zero-to-CPL+IR with no other experience to set you apart from the rest and help get you an interview. Have you made the effort to go and meet the various operators/chief-pilots/recruiters face to face? You might not want to limit your options to offshore if you want to at least keep your hand in, I know of a handful of places looking for fresh instructors...
