A Resume is a document prepared by a job-seeker which is presented to a prospective employer and contains information about his/ her educational qualifications, skills and past work experiences.
You need to use bold fonts for headings such as "Educational Qualifications", "Work Experience" etc. The format should reveal your strengths and also use italic font wherever necessary. If you submitting a resume online make sure you use keywords that match your job as most job portals use online programs to match potential employers with job seekers.
If you are in the same industry you can have your past experiences in chronological order. If you are changed to some other industry recently then make sure you give priority to the last work experience. Because if your employer looks at the old work experience he may think you are unrelated to this industry.
You should state a clear and strong objective and goals related to the job applied. This would attract the employer as it proves that you want to excel in this area.
You resume should include more than just your work profile or positions held. You can include any appreciations or achievements in your past jobs. For instance you can state how you improved cost-cutting methods in your previous organization, increased sales by implementing sales strategy or enhance the revenue of your past employer.

They will charge some fees for this service. But in return you would get a professional and powerful resume that would definitely increase the chance of getting a job or Interview-call.
