I would find out what your town spec's are as to when they call you out, what insurance do they require (if you hit mailboxes or parked, buried vehicles), and how much are they willing to pay (per push/per hour/per inch)? Then figure out if its worth it to be in the "plowing game"? Our township used to sub-out cul-de-sacs, we have a few hundred here and their 2 ton trucks couldn't navigate them well, then I was told that that the township called the subs at 4" of snow, as a private contractor, I had my contracts set up at 2" to push snow. 4" of snow is A LOT of snow when tring to push the stuff around and its harder on the truck, plow, electric pumps, etc.
Just a few things to consider.
Other than that- it seems like a do-able truck for your needs.
