aircraft leasing
if you are looking for the beast lease (to maximize profit if you have the customers) then you'll want to look at paying a monthly fee (payment / lease payment, etc) and an hourly reserves cost for engine, accessories, prop, governor and avionics
in the big boy world (not 206s) they have what are called ACMI leases - where the operator provides (via hourly, daily, weekly or monthly lease) aircraft, crew, maintenance and insurance - the customer just pays for fuel and handles all their own marketing, booking, etc. (financial risk)
a colleague and I are seriously considering buying a 206 - let me know if you have a turn key situation with revenue & the only reason that you are considering a lease is because you are avoiding conventional financing
