Easiest way is to complete level 1, and once you start level 2 and get past the first tutorial speech. just sell all the barricades around the map. If that doesn't get it for you, just place a couple barricades (as they're only 25 to place) and sell them. Once the achievement pops, just restart the level and play normally.
