Copper washers/ copper wire (Glen Burnie)

Hi there, I’m looking for some copper washers and copper wire scraps hopefully more than a few inches long. I’m a jewelry maker and I remember somebody saying having a plumber as your best friend is great to get free copper so I just thought I’d put it out there I especially I’m looking for the Copper washers ( any sizes and a mixture would be great and don’t worry about rust, I can clean it.also, if you have a lot of cables that you aren’t using anymore that you know copper is inside, I have a tool to strip away the cable so if you have a bunch of cables that you’re no longer need that would be great too I can take care of that.)for some jewelry designs that I have that I would like to make. I really appreciate it. Thanks in advance.
