Ice hockey goalie question?

alright so i have played hockey since i was in 2nd grade, i started out as a roller hockey goalie, and i then went on to d, then rw, c, then lw, well anyway i stopped playing for 4 years and i am now a freshman in college. i really want to start playing again and am looking into goalie, i am 18 now, is it too late for me? or could i go to a goalie camp for a week or so then play for a house team? or mens league? where should i start, and is there any room for me to grow? like can i move up at all or would i be in mens leagues for the rest of my life. thanks
