I don't know about Pinnacle, but if your looking for a private jet job I would suggest passing out resume's to the both FBO's and charter operator's. I know a couple of captains that when they are in need of a F.O. they'll hit up their local FBO for pilot resumes. Another tip is just to start talking to the pilots on the airfield. They usually have a pretty good idea of who's looking for help or other great tips.
