Whirly definitely is young enough to start a school like that, and when I get my FI(R) I'd be more than happy to work for her. We do need more schools like that!
As for:
If you do advertise them [your state-of-the-art aircraft] explicitly you will in effect be saying that the 1970s Cessnas you have are a pile of junk
I disagree. It all depends how you phrase it. How about, just as an example:
"Whether you would like to train in modern, high-tech aircraft with state-of-the-art navigation equipment, or a classic open-cockpit aircraft such as the Tiger Moth, or anything in between, we have the aircraft to suit your needs."
Prices would, of course, reflect the aircraft, so that those who want modern equipment would pay for it, and those who can't afford modern equipment would still be welcomed too.
Now, all we need is a bit of funding, a few more willing instructors, and an airfield to base ourselves out of......
