The following is based on some data Cpt. Brick got from an Alaskan charter
company and a few ticket fares.

Ticket price pax per hour: aprox. 134 $ / pax *h

Cargo fare per pound weight per hour: 0.55 $ /lbs. * h

( the 'time' you charge being your 'xp trip time' plus 10 to 15 min. for
ground operations, unless you're really travelling from apron to
apron...)

You might want/have to adjust these rough guestimate values to fit the specific circumstances for your flight. Dangerous routes, passengers, cargo or flight circumstances require expensive insurance policies. Emergency jobs require higher priority and block more precious and expensive ressources.
