Hi again! I graduated from college ten years ago, and completed my masters a few years ago. I wrote my academic writing sample on my own, last fall. In addition to two academic references, I asked my current supervisor for a reference. If you want to apply again next fall, why not enroll in a class this summer for a reference, or ask a professor outside of English, or ask someone in your field. You could also write to the programs that rejected you to ask why (I did). You could asks friends to read your essays; you could write to English depts. in your area to ask if a graduate student would be willing to tutor you for support with your essays. You could build your resume with a teaching or tutoring job.
