"...Why don't you explain that " financial model " for the forum to analyze ?
You claim " you don't understand the basics of a financial model. " Given that statement you obviously think you do .
So explain away for the forum to read ...."
Firstly, do you understand what a financial model does? Do have any experience with modelling planning and estimates for project builds? How much do I need to dumb this down for you to be able to understand the process?
"...So if they don't know which brand, which type, how many or how much they have to pay for the sites, how could they possibly know the cost ??..." This comment highlights to me that you fundamentally don't understand financial models and the fact that you can model multiple scenarios concurrently to provide an estimated cost envelope.
