The flies in the ointment, so to speak, in your analysis are at what stage of development did they project 2.8B sold, versus where they are, and how long will it take to get there, and with how many construction stages. They are currently selling 50M per month, so that's a pace of a little more than 1/5 of 2.8B per year. 2012 sales look to be little more than $1M, imo.
So, huge ramping to go, over an unspecified time frame. Also, no one ever said they would sell all high value prawn flies. There are some seasonal issues, maybe also supply constraints; more likely 1/3 - 1/2 hi value green prawns.
You can still dream with these numbers, but not outrageously, like your numbers, imo.
I would guess very roughly more like a 5.6B capacity in 2-3 years with average price of $75 per 10,000. Therefore, at capacity well down the line: $42M revenue generating $21M gross profit, if they get an exceptionally generous 50% gross margin.
