Has anyone had any experience with professional resume writing services? Which service did you go with? How much did it cost you? Did you go for a cover letter too? What about these linkedin profile makeovers? Did it increase the number of interviews you scored? What was your overall satisfaction with the writer/service you hired?

Yesterday I decided to randomly click one of those 30 second resume critiques and today when I got the feedback, I was surprised that a real person went through my resume and highlighted key issues that I can agree on. Or at least, they convinced me into agreeing. But I never knew that hiring managers use special filtering software to eliminate applicants. I have been writing my resumes myself for the last few years but now I am wondering if the playing field has changed and I should up my game by investing a little money. The service I saw was about $150 for resume, $200 for resume & cover letter, and $350 for the all of that plus one of their top writers. Another service I saw was quoting prices in the thousands of dollars.

What is a good price to pay for this sort of thing? Anyone have any recommendations for particular services they have used?
