Mobile Wire Scrap Yard- Need Advice

I was kicking around some ideas of future scrap endevors and the idea to start a mobile wire yard came up.

I would go to local business with scrap wire and offer them a percent of what the wire is worth to me. They would have some type of container and every week (or every two weeks) I would come and buy the wire onsite and write them a check that day. I am thinking pay them $.60-$.70 on the dollar or so? Thoughts on that? I would also strip the wire that I think is worth stripping and sort the other wire by grade.

Nobody to my knowlege offers this service.

Let me know what you think, I am young and ready to learn. I currently run a F150 and 7000# dump trailer doing mostly ferrous with some non-ferrous here and there but with school it is hard to make that work. My thought is with a set schedule I should have time to do this in my spare time.

Thanks!
