Like Lift4Size said, find a bench /deadlift meet.
as far as waiting till your ready. forget that! you will be missing out on a lot of fun.
Every meet I ever entered, my one & only goal was to improve, to lift more at this meet then I did in the last. If I did that then I won.... no matter where I finished in the standings. I can't control what other lifters do, nor did I pay attention to what they were lifting. Sure I cheered them on! but I didn't pay attention to there numbers. After I was done I would fine out if I finished in the top 3 if I did I would wait for the awards. If not I found the winners of my class told them congrats! and left . Feeling great or not so great depending on how I did. LOL
Find a push/ pull meet at least 8 weeks away, train for it and go have a blast.
