I have been in your position before and have kids your age. The management of a corporate jet is almost a full time job without flying. CesCom, FMS updates, maintenance scheduling (both scheduled and unscheduled),trip planning, passenger & crew lodging and ground transportation, keeping the plane clean and stocked.
Just wanted to give another option.
You alone could manage the flight department for a monthly fee, split by the owners. All flying could be paid on a daily rate by the partner making the flight. The going rate for an independent is around $600.00 per day. If they pay for both your training you could make it $400.00.
If you could get $2000.00 month management fee and $400.00 per day you can do OK. After a year if the flying slacks off -go up on the daily rate. Also have a 3rd (independent) contract pilot available for sickness, vacation, etc.
If they do fly 500 hours per year your earnings can add up. If not you're being paid for the work you do.
