50% of my work related time is spent milling trees I've removed, or exotic species my associate companies have removed. The other 25% of my time is spent drying / storing / planing / selling the slabs. The other 25% is spent doing actual tree work, primarily large removals and crane work to produce more logs to get through my mill.
It's a hugely successful business model if you can tap the market, other companies benefit from pushing big logs your way because they don't have to dispose of them.. which at least in my city is a problem. Just have to tap into the buyers market, mainly successful urbanites who like that "Rustic" look.
Use words like "Live edge" "Salvaged" "Reclaimed" "Repurposed" "Recycled", they eat that shit up.
