Well...I'm not sure about contact info or hiring, but at RDU there is:
General Parts/Carquest (Hawker/Beechjets)
Progress Energy (Citation I think)
SAS (BBJ/Citation X/Beechjet...tough department to get into I hear)
Martin Marrieta Materials (Citation XL)
Bayer (Just got a LR55 I think)
State of NC (Citation/BE200/C441)
These are just a few in RDU I can think of right now.
Piedmont operate a few aircraft out of RDU on their certificate. You may want to check with them for contract opportunites.
I think Centura Bank in Wilson used to have an airplane. Dont know if they still do, but they are relocating the company HQ to Raleigh soon.
