sell that wire on ebay or locally! Youll make way more since its still wrapped - full spool. that spool probably weighs 50lbs and is not very ideal to ship...though I would go on FedEx and create a shipment to check out the price. make sure u choose a place that opposite from where you live ie if you live on east coast, find some random California address.
Also is that green wire for internet? Again, I would try locally this time for that.
By locally I mean websites like craigslist.
