No spell will give you money, you will need to work (a job) to get a cash flow, however I heard you can do a honey jar spell to help with luck to increase your chances on getting a job. I never tried it though.
There are spells and rituals to draw money to you, but they serve to augment what you are doing to gain money. Are you out looking for a job, trying to earn money working on your own, or are you just trying to cast a spell and expecting money to just "poof" into existence for you? If it is the latter, you will be woefully disappointed. Your magic should be supported by your actions on the physical level. If you do a spell to get money, and then sit around watching TV all day, you won't get any money.
There is a story about Crowley (Yes, I know he has issues.) when he needed money to pay his rent when living in Mexico. So, he did a ritual to attract money. He was so confident that it would work that he took his last two dollard and had ice cream after the ritual. It worked, and he recieved a royality check from his writings shortly after. Take note that he had already done the work in the physical level to be able to attract the money (writing his books).
