Why use a resume writing service if you can write a CV yourself? The best answer is because other people can write a better one. Furthermore, people that have been in the industry you are hoping to work in will be better able to communicate on the same level as the bosses and HR staff that still work in those industries. In addition, you have a lot of competition, and if you find a good resume writing company, they may be able to put you ahead of the competition.
Save time and effort
There is a good chance you will have to send out a lot of resumes before you get a job. Your best bet is to knock one together yourself and send it out, and then send the same CV to a resume writing service and have them create a more professional and in-depth CV. Once you get your professional resume back, you can start sending it to jobs as part of your application. Doing it this way means you are still looking for a job without any down time, and it means you are putting your best foot forwards once you receive your resume.
You may get a better position with a better resume
There are plenty of real-world examples of people getting better jobs because they entered at a higher level than they would have done otherwise. You can save yourself years of hard work by getting a good job to start with, and a great CV will help you do that. It is actually easier to start slightly higher up than it is to start at an entry level and work your way up.
Use it to get a new job at a promoted level
If you are struggling away and cannot get a promotion, then get another job with another company at a promoted level. There is no harm in applying for the promoted level. Sure, many companies will not give you the time of day, but with a fantastic CV and a positive attitude, one of them may give you a chance. You could even offer to start at a lower wage to prove you have what it takes to do the job right.
It is easier than writing your own resumes
You have to admit that having an industry expert write your CV for you is easier than writing it yourself. If you are think it is just a case of putting your information in the right boxes on a template, then that may explain why your resumes have not gotten you a job yet.
