It really depends on the career path you wish to embark on. No spell is going to grant you a job in that field without having some motivational background. For example, if you wanted to be a Marine Biologist, you won't be hired as one without the educational credentials to support your hire. That's not to say you can't get into that line of work, just perhaps not that exact title.
I always tell people that the spells won't make things happen if you aren't actively looking into this on your own. They will, however, enhance your chances and likelihood of falling into the right direction.
Think of what it is you want to do and start researching positions either in it or aligned with it. Lets use an attorney. You want to be an attorney or lawyer. This requires schooling and passing the BAR. (speaking from the US only). You can start by getting a job as a Legal Aid or clerk. This requires little educational credentials but will expose you to learning more about the position you really want. So, you could apply at positions like this, using a career spell or job spell and work into the field that way.
Since you stated you have already started the credential part of the work, getting into the field is where your focus should be and starting at the bottom, sometimes, is the best means. There are many spells for jobs. I would suggest writing your own. I tend to like physical objects in my spells and I often use a business card to the place I have applied in the spell.
But be aware of things, not to deter you from your goal, sometimes the forces of the universe are more powerful then our spells, will and intent. Sometimes you will be rejected over and over and not understand why. Look at this as a push in a different direction, in that you are meant for something else, greater than what you thought you wanted. I always try to keep that perspective alive in case things do not pan out, try to look at it as if you are being pushed in a different direction. Who knows, it may lead to something you never knew you would want to do.
In any case, good luck! It would seem you have the right mind set and awareness of what is needed. I hope things work out in your favor.
