Labor vs Diesel

My town has a population of 40,000 people, 3% of which, or 1,200 people, are unemployed. My town employs a vast fleet of diesel powered vehicles to remove snow from it's many delightful streets, and a smaller private fleet that maintains driveways by commission. Research on the internet (typical) has led me to believe that a truck with a plow costs roughly $30 a job for a simple snow-shoving operation that takes perhaps 10 minutes, and involves only a few passes. If I offered $10 an hour to three people, I bet I could do a more thorough and precise job, even offer individual car cleaning, all the while offering an excellent exercise program, and a starting wage that's well above minimum. Assuming they do the work in half an hour, I can pay them $15 an hour, and spend the extra $8 per job on supplying them with protein-rich local organic snacks. As a worker in this profession, your only equipment concern is your shovel, as opposed the the investment in time and money to own a truck, the initial payment of thousands of dollars, the inexorable upkeep, the insurance. It wouldn't be a living, because you'd only have work during the months of snowfall, but at that wage, and with in mind that there are very few requirements for such work, you could certainly amass some spare cash while helping displace some of our misplaced dependence on extremely cheap energy.
