What is the best way for my husband to advertise his snow removal services?

Make sure his ads and flyers reach the customers at the day of the first snow. This is really important. Then later use the weather forecast to decide when to advertise. Only advertise around the days it is actually snowing. Timing is very very important. Make also sure to take advantage of word of mouth, get a good reputation. He don't need a website, snow removal is a seasonal business. People don't go on the internet to clean their driveway.
