One thing that I always try to do when doing a spell for employment is to not focus on a particular job. I always try to cast the spell with the intention that my husband will get the job that he is meant to have, that he will be happiest at, or that will meet his needs. Focusing on a specific job narrows the opportunities that the Universe has of meeting what you really need...which is A job for your husband.
When my husband was out of work I would take one of the 6" chime candles in green (since it is about making money), and anoint it with cinnamon oil. I would light it while clearly stating that as the candle burned it would open up the Universe to fill my husband's need.
You can also burn some allspice as incense to attract money, or have him carry a sachet of basil in his pocket.. A tonka bean in a red flannel bag which is carried to job interviews can increase the chances of success.
