Your background is certainly an advantage if you are looking for a mustering job, which is a good way to gain hours and flying skills. If you are looking for any other type of helicopter flying then you will encounter the familiar 'Catch-22' situation. You need hours (experience) to become employable and the better quality of those hours (PIC, night, CTZ ops etc), the more employable you become. Other ways you can build hours are to become an instructor, or if you are able, join the military. Some of the larger companies employ co-pilots so sit for your IREX exam and get yourself as well qualfied as you can. Don't give up as I believe that you are in a good position. There are lots of us old buggers that are coming up to retirement age and it's enthusiastic people like yourself who will be filling the vacancies in the next few years. Good luck.
