Hahahahahaha!
Gordy has written exactly what I was thinking.
That said, your best bet might be a bell47 as they are now annex 2 they are considerably cheaper and easier to maintain. Low hull value and low flying hours also keeps your insurance down. We have a gaggle of Bell 47s in Yorkshire so if you want to discuss ownership of one drop me an email.
But unless you know what you are doing making money can be difficult. I would never lease a machine to a flying school without strict agreement on who flies it and who pays for the unscheduled maintenance and damage etc. I'd also insist on them insuring it.
