Is this in all one length, un-tangled if so get a pull through stripper it will be cheap and easy, 2 tones is probably about 5 grand worth of copper, so unless your going to keep getting wire I wouldn't invest in anything too crazy. Are you going to need any paperwork for all that copper, if so hopefully you can get back in touch with who you got the wire from.

My sister keeps bugging me to move to AUS if there is that much of a scrap market maybe I should?
