Your best bet for researching this project will likely be to take a look at some of the many existing charter/fractional ownership companies which are out there;
There are others too, but I think the three above account for a lot of the Teterboro traffic, the private jet charter market is rather crowded. Back in 2008 they were all signed up for far more aircraft than they could actually buy, and when the credit crunch hit Wichita was suddenly flooded with white-tails when they all cancelled their orders, it's only just recovering now.
They all basically operate on the business model of rent/lease/lend, but generally, the bank owns the asset, the charter company just provides the crew, pays for the maintenance and tries to eke out a profit from the approx $4000/hr operating cost of whichever jet is being flown. Some companies are clever and offer charitable compassionate flights to hospital patients or people with disabilities to get the tax breaks. Savvy accountants will use aircraft depreciation and operating expenses to their advantage as well. I expect the state you base your aircraft in has an effect too, assuming the model is US based, as some have higher luxury asset taxes than others.
But the best explanation of the business jet business model I've come across is here (two parts);
Basically if you're smart, the get the bank to buy the plane for you, and make the plane work for itself and pay the mortgage on it's own, meanwhile you have a business jet for your own purposes at your disposal - this is all dependent on demand and availability of the aircraft. An older hangar queen will say goodbye to your bottom line if you can't keep her in the air.
