What you need to do is contact a leasing firm, they will let you know about prices, they probably won´t be by the hour, but by the month (with a min. of hrs. per) and require a medium to long term contract, if it is leased dry (no fuel, or crew) it will be less expensive, but they will expect the carriers crew to undertake specific training and have a set minimum of experience.
Good luck!
