I don't have any room in my games I'm playing in right now, but maybe check with the staff at Phantom of the Attic on Craig Street. Just make sure you go to the game store and not the comic shop (or go to both, they're right across the street from each other).
Black Lotus Pizza in Bloomfield tried setting up an adventurers league but I don't know if it ever picked up, they might know people who are looking.
