I need a job

This semester was the first time I wasn't working while I was in school. I thought that I could actually make it through December on just my school money but children are expensive. Over half of my financial aid was spent on daycare for my baby. I need to find a job so I can finish out the semester. I didn't want to get a job until I graduated so I could find a job in the field I was going to school for. I don't even know where to start looking for a job. All of the job search engines have little jobs. I haven't been in school for the last four and a half years to only find jobs at Circle-k and Ross. So if anyone knows of a good job int the finance field please let me know
