What comes out best is if a group of people gather at the center and recite the Arya Sanghata Sutra nine times. It comes out best if this is done by a group of people at the center.
If nine people come, then you just have to recite it one time, as you can count each person’s recitation as one time. It is a long sutra, so it could be done over a few sessions.
The dedication should be for you and for your enlightenment, and then specifically for the removal of obstacles to finding job.
The other practice that come out for you is to recite the Norbu Zangpo Zung mantra every day.
