I know it is possible to trigger that quest immediately upon joining the guild, but the exact requirement to trigger it is unknown. The best guess I have, based on her dialogue when it does finally trigger; is that you need to up your step counter by walking around more.
You can continue progressing through the game, completing other quests, etc., just make a note to come back and check when this option does finally unlock.
