NeilB,
you are going to find it very hard to get a start with that resume.I can tell you that most if not all the companies in Vancouver will not want to see you and will have insurance policies which exclude you anyway.Proximity of mountains, coastal weather and overall knowledge required to operate to the standards expected of helicopter crew in BC is their excuse.
My suggestion is that you don't waste a day in the mountainous areas and head straight out to the flatlands.There are companies in Alberta, Saskatchewan, Manitoba and the territories who have 500/206 aircraft and relatively low requirements for crew. The reason they have low requirements is that they don't want to pay you much and will work you hard, so you go there knowing that and also knowing that all parties understand you are there long enough to get the time to get a reasonable deal. Most people do a season or at the most two with these companies then move on.
If you do get on, don't expect good pay, conditions, equipment or fair treatment. Everyone will know who these companies are so it won't be hard to find out who they are. It will cost you to get around to see all these people, but its the only way. Phoning faxing is a waste of time. They'll want to see your face and chat. Might even be worth buying a van, living in it and driving until you get something.
Good luck.
