I'm drooling reading your list... If you like taking things apart/ have a torch, I would find out what categories your local yards like metal to be divided into for the most profit or which scrap they prefer and then get to work. I work with three different yards where I live and have been blessed to build up good repore (sp?) with all of them to bring them the kinds of scrap they prefer to deal with.

If you don't want too much dirty work, pull off the really nice stuff to sell then get some bids from people who will pay you for it as is/ on location.
