To give a quick overview of corporate north-east US....
Day rates seem to average US$500 to 800 per day, regardless of length of time on duty/hours flown. Sounds nice, though this assumes you are current in the twin being flown and have probably established yourself in the area for some time.
General charter in singles and tours are around mid to upper US$40,000's , though tour pilots get tips!
Full time corporate-type First Officers in twins can be from mid US$50,000's to US$80,000's depending on type of corp owner or whether Part 135 charter operator.
Captains seem to be around US$60,000 for single pilot charter in twins like TwinStar or EC135, to US$90-120k+ for the name-brand flight departments.
Seems like alot? Then again, FOs often need ATPL and 3,000TT and captains 3,000-5,000 with twin experience to get an interview. All fly IFR regularly apart from the winter icing days.
Some work a handfull of days per month but are on a pager and must be ready if called. Others worj x on / y off and know to a more certain degree their work schedule (though not where they'll be flying to til the night before).
Housing prices within an hour of northern NJ, Whiteplains or the Conneticut based programs are very pricey for something you'd like your family to live in and take a big bite out of your income.
Still, a marvelous job if you can get one. Love it to bits. Persistance and timing are often key to getting in.
