Transfer Essay for Purdue

Can I PM someone to help give me honest advice? It has been about 4 years since I have written to a college, or academically, due to work. The prompt is: Please provide a statement that addresses your reasons for transferring and the objectives you hope to achieve. (250-650 words)

Also, does including a resume in your application help any? or is it not really part of the decision process?
My essay focuses on military experience and how it has affected me to pursue my academic goals again. Is it emphasized too much? What should I speak more of, or speak less of? Thank you in advance for your time!
