The storage unit isn't a bad idea at all. And, honestly, there will be one literally three minutes from the house we're planning to buy. The question I would have to answer is whether or not the cost will justify itself in profits, as I'm already working a full time job currently. What I'd like to do eventually (as I build clientelle) is go part time and scrap more, so that may certainly be a good idea. I'm hoping once we settle down at the house, since it has some land, the area for breaking things down will take care of itself.

Thanks for all the ideas so far. I don't have a grinder, currently, but that may be worth looking into.
