Hey I reckon that saturation of the market counts for quite a bit, not with cv's but with turning up and meeting people and then giving them your cv. I guess it is much easier for them to give you a job if they have met you and know that you are not completely different to them. I drove 11,000km and was meeting with the 80th operator I had visited when the 8th operator I had visited rang and said there might be something there for me if I could get there by the weekend, 1200km later I was there two days early and got a job within three onths of getting CPL. The market was a little better then but My point is that it is a gamble for an operator to get someone up just from a cv , I dont even know if any of them do it, and when one of the many operators out there has an opening, you really want to have met him/her.
It can be a great trip as well. good luck
