There will be plenty more job quests to do when the cap is raised. The entire idea is to start at the bottom, and become the Paragon of *insert class* Excellence your character was destined to be. The level 36 quest is likely just the halfway point at very best.

Just be glad you didn't do the Pugilist one. First quest has you picking up change thrown on the floor from some rich asshole who owed the guild money, second involves being used as a part of some conspiracy. I assume the 36 quest resolves this, because man is it unsatisfying being an errand boy.
