Freelance editors normally do not double as literary agents. Not only is it not our area of expertise, but it can actually lead to ethical quandaries. There have, unfortunately, been cases of literary agents saying that potential clients’ work “has potential” but needs to be edited (by them or their employee), for an exorbidant fee. It would also be possible for editors to give the impression that they are guaranteeing publication of a project, when that is something no one but a publisher can do. Many professional organizations forbid their members to combine these two roles, to avoid a possible conflict of interest.
One thing is becoming clear to me. Authors and editors have been mistakenly pitted against each other by a self-publishing system that is not currently working. Remember in the scheme of things that self-pub is very new, only a few years old. Twenty years ago, publishers put out a selection of the best and most marketable books. Editors were well-educated and got paid a fair wage. Authors received advances and royalties.
Obviously there is a big difference. I actually started with screenplays (with some mild success) partly due to hearing that as long as you have a good story, the grammatical errors won’t be a big deal. Well, that was not true. Maybe if a producer liked the story or I was already established but every contest I entered always came back with feedback about the grammatical errors. Even if I won or placed as a finalist, I always received critique on that. Very little is spelling error, it was more about structure, etc.
