You don't have to sort it yourself.
The hardest part of clearing a garage isn't the hauling — it's staring at ten years of stuff and not knowing where to begin. That's what I'm for. You point at the pile, I load it. If you want to keep something you spot along the way, we set it aside. Everything else goes in the truck.
I'm a UVM student running this out of my own trailer, and I've cleared plenty of Burlington garages, South Burlington basements, Williston attics, and Essex Junction sheds. Every one of them was full of things people said they'd deal with later. Now's later.
