new to scrap metal sells

I am new to scraping metal. I got interested in it by finding out how to strip copper wire and the price and how easy it would be to make money at it. I am into different auction storage, online, any where to find things to sell on ebay or swap meets and maybe find some scrap metal to sell. i am retired so it will keep me busy and make money at the same time. I am tying to start a business of ebay and swap meets. hope to learn more about scrap metal industries.
