Why not make your own? Find a background you like, such as a posterboard or a piece of fabric and attach library pockets. You can print signs/labels for the jobs on your computer. Write each student's name on an index card to put in the library pocket when it is there turn to do the job. This way, you can make it look however you want.
I just used colored sentence strips cut in half and wrote the name of the job. Then I had the kids names on start cut outs and slid them into attached paper clips. It was super easy, I am debating whether I want to do it again, but since I am moving down a grade I am thinking about listing their duties that come along with a job so I don't have 50 questions about what they are supposed to be doing
