Few really know just how well one can do collecting roadside items for resale. Often times people don't know exactly what they once had and are in hurry to part with it for a variety of reasons (time, space, a death in the family, moving, divorce, etc). Even more frequently, these very items don't even need repainting and repair. I could tell your stories of the HUGE scores I've landed until both you and I are blue in the face- but we'll save that for another time.
I also run ANOTHER YouTube channel where I chronicle some of those finds (and report what they sell for via Facebook marketplace, yard sales, of flea markets). Check it here- https://www.youtube.com/channel/UC3ePK6dw_7L5dlmkGZ5vVnw
Speaking of which, in further luck, we recently had a chance to pick through an abandoned 1850s house that was soon to be fully demolished- the house AND everything in it. Yes, we had permission to take anything we wanted as it was all destined for the dump. The owners had recently hosted an estate sale, but there were so many items in this hoarder house that it really didn't make a dent- and that is where we came in- cue to video.....
Basically, here is proof that there are outside-the-mainstream ways to make a living- MANY of them. It just takes a little know-how, and a little elbow grease (and maybe a dust mask or two).
