If I were you I would keep writing for sportscolumn as much as possible.  People do notice you here.  Accept anything that gets tossed your way from a bigger site.  I'm currently working as an "analyst" for water polo for College Sports TV.  Granted, I played water polo, but the point being is that you gotta get yourself in the door.  Now they got me in for water polo, I at least know who to beg, plead, bribe, etc. to let me cover college basketball (which is what I aspire to cover on a full-time basis).
