Diamond Player LF Teams to SUB/FILL for...

Like the title says, I am looking for teams Gold+ To fill in/sub for when needed. I would join a competitive/serious team however my work hours are random and often leaves me with off-peak play time. Therefore I would like to offer assistance to teams in need of a swing player, in which case I can fill for any role and be comfortable playing up to challenger level games.
