I think that if your job search strategy begins with submitting applications -- so many applications that outsourcing that task makes sense -- you have the wrong strategy. This seems like polishing a turd, in other words.

A good recruiter (paid for by the employer) or agent (paid with a percentage of my gross) will have contacts and inside tracks (unadvertised positions) and reputation in the business domain or geographic area. A good recruiter or agent will bypass the "submit an application" online step altogether and get your resume/CV in front of the hiring manager and line up interviews.

Job seekers shouldn't have to pay to apply for jobs. I think most adults with some work experience understand that, and view any supposed agency or recruiter who does charge for applying as a scam. I'm not saying you're running a scam with neverapplyagain.com, but you're getting into a disreputable niche full of scammers.
