I realise it's difficult to get a flying position doing paradropping Cruise Alt however, I just left a DZ being offered a job and there 'was' a position available but is now taken. Keep on trying, call every week if you can. It is very much a right place right time affair I'm afraid. I was lucky in that the very first place I called had a position available and I started virtually straight away. Very lucky I was.
Most of the DZ operators have only one aircraft (C206 or Islander) and have only one pilot as they operate only a few days a week. Go for the big ones that operate throughout the whole week. The DZ I was with had roughly 5 different pilots on call/roster throughout the week.
