First get into a relaxed state by meditating.

Then chant as often you want (at least three times):

To the Gods and Goddess,
I do Pray, Help me find
A job that will pay,

Water,Fire,Earth, and Air,
This job pays well with plenty to spare.

Chalice, Wand, Pentacle, and Knife,
With this job let me be set for life.
By the power of three times three,
As I Will, So Shall It Be!

Then meditate and visualize how you get a job offer.
