In Short, I want to trade about 50,000 units per month of Nitrogen and/or Oxygen isotopes for the same quantity of your Helium and/or Hydrogen isotopes, with no ISK changing hands.
I am a miner located on the border of Black Rise and Placid, but need all four isotopes for doing composite reactions. Perhaps there is someone in a similar situation in Minmatar or Amarr space who would like to trade on a regular basis?
