In my opinion the Trust should be talking to the various supporters groups whilst at the same time as talking to potential investors then when they have investors lined up with a valid, thought out and costed plan then go to the wider supporter base get their backing and then go to the council and push forward the proposal.
This would be VERY difficult as the price for NTFC can change by the day, like it did a couple of years ago when KT quoted a price to someone and then a couple of days later quoted a different price to someone else, the difference was £1M !
