I am a research student at the moment, but it has occurred to me that it could potentially be profitable to be a "pre-reviewer". I will explain what I mean.
A pre-reviewer is not an academic or someone who works at a university, but does independent review of papers that are to be submitted to conferences or journals, thereby maximizing its acceptability.
I believe this could be a profitable career path that also allows me to do research on the side, but is this feasible? Does such a career exist?
I am also not sure about the ethics of such thing. But this seems on par as using another peer to read your paper (at no cost, of course).
