A professionally written resume is an investment that can offer a high return on your money. For example, if you earn $40,000 per year, this averages to a little over $150 per day. Say your resume cuts your job search by just 4 weeks, then your return on investment is over $3000 to you. Wow! You can certainly try to write your resume, but the cost of having your resume written by a professional should not be a major factor in your decision.
