Have you checked into work study with the financial aid office?
Have you visited the Student Services Center at your college and inquired about campus job opportunities? They may have suggestions for local jobs and/or serve as a valuable resource to assist you with your search.
If you're flexible with your options, you might consider checking the Arlington community for job options. Many communities like to support the students of their college and have available employment that will not interfere with your studies.
Hope this helps!!
