NJA Capt is right...there is no set pay scale for NJI. However, the basic starting salary in the past has been about $70K for a new hire F/O off the street, and $110K for Capt (after upgrade) with only annual cost of living increases. F/O starting salary could be augmented a bit depending on the new hire's Gulfstream experience.
This is from a few buddies of mine working on the NJI side, and may not be current for '08.
