Looking for a Tree Lamp or Hanging Arm...

[Carrera75]

I am looking for a tree lamp or hanging arm or whatever this thing is called. This would be attached to the back of the stand and the light fixture is hung on it.
Does anybody know where I can get one of these locally or if somebody is open to making one in exchange for some awesome Rics then get in touch. I should mention that I would pay for the materials if somebody was willing to make it. The rics would be in exchange for your labour.
