Sounds like theres lots of runners getting airline jobs lately compared to other twin piston drivers. But maybe thats because runners tend to have more experience than the average twin piston driver in any other sort of charter company. Yes bankrunners do fly lots and are exposed to all sorts of nasty east coast weather and plenty of night hours too. You'll probably need a few hours to get a job though - 1500 hours total with 500 hours multi command sounds pretty normal.
check PM's.
