RE:RE:U.S.$ 73MThese are the two Counties that have issued the $100m contracts. How many entities of about like population/highway infrastructure size are there in N. America, Europe, Australia, New Zealand? Multiply that number by C$100m, then divide by the number of companies capable of serving that market. Bingo! You've just completed a rudimentary market survey. Be conservative. Won't matter. It'll still be absolutely huge.
