Hello everybody new here from Brooklyn

I need some advice . New to scrapping been doing it for 2 weeks with a 20 ft box truck that was my work truck . Long story short started scraping because I lost my job . Does any body know if I need a business sticker on the side of the truck? I know I need commercial insurance and a dot number because the truck weight is 14500 gvw. Not sure if I need a business name or LLC or anything. I scrap in Brooklyn and queens and don’t drive very far. Any help would be greatly appreciated. Like I said I lost my job but scrapping the last couple weeks I actually made more than I was getting paid.
