As the man above me has said, you can't buy your way into the trusted member's club around here, so don't try it.  Negative rep gets handed out like fucking candy on this forum.  Just be a member here, post constructively, and do some trades that you need to do (read: not to build reputation alone).  If you are able to be trusted, this will eventually show up on your feedback here.  But it takes time and there's no substitute for time.
