I have been doing this in a small way for years now. Buy off season recreational equipment in the off season, repair refurbish and flick it off as the season starts. Think Campervans, convertibles, motorcycles, surfboards in winter. When summer comes start buying winter toys and selling summer ones.
BTW: that firewood business is a tough one. You will be very fit by the end of the season, slinging wood around. The complement to a firewood business of course is a tree removal business. This way you get paid both ends of the deal.
Heres what you need: trees, good chainsaws, a tip truck that holds a cord, a storage yard, hydraulic splitter, cheap casual labour.
