When I lived in Burlington, some of my lawns clients wanted me to do snow removal. These clients where all within my neighborhood. So at the beginning I would walk to some, or throw the snowblower in the back of the van (on a cargo cover, yes Weathertech!) Then I got a ramp that attached to the hitch the following year. 3rd year I got an enclosed utility trailer. Which is posted somewhere on the forum. I would grow year to year, as my time would let me. As the kids are both in full time school, I can expand again.
I have decided this will be my final year for snow removal in Burlington. I am in Ancaster now, about 22 km away. I have hired someone to manage the route this year, if he needs help, I will help him. I am going to sit this year out mostly. Next season, I will advertise around here. Won't be too hired. I already have 6, without advertising. They just come up to me. When I have lawn mowers in the trailer. So I will probably do 4 of them, as 2 are in my court, and 2 are on the way to my kids school this year.
As far as a truck. I am not sure how you would remove snow from a driveway with a plow at the front. You going to push the snow up to the garage door? And a lot of the houses around here, have driveways that would get marked up easily by the plow.
