Middleman

As I wanted to sell my Eternity last time and I did not find a middleman for it I want know know if there is a wa to be one. I would also like to do a middleman job just for helping people, because when I needed one there was nobody.. I know my Rep is not that high but that is caused on less trades I did in the past.
