Groundloop - I'm no entrepeneur, the idea is to perfect the plan & basically hand over the whole thing to a willing investor, who'll then find someone who is an entrepeneur. If we reach that stage then myself & the people who are working on the project will probably cease to have anything whatsoever to do with it, which will be heart breaking, but that's life. So that's why I was consulting spotters about fuel burn etc.
I did think I'd have to defend myself a lot more, so I appreciate the lack of criticism & I'm taking onboard all advice that's being posted on this thread! It's much appreciated thanks.
