First, you have to understand that there are good editors and bad editors. Just like in any business, there are some people who will just try to take your money, and no, they probably don't have much of value to offer you. And then there are the other editors...
I have worked as a writer for half a dozen years, and have spent lots of that time editing and critiquing for others. I've gotten skilled at expressing why something works or doesn't work, and even has I have honed my own craft, I've helped others to hone theirs. I can do basic proofreading to catch spelling and grammatical errors and the dreaded homonyms, sure, but I can also offer so much more.
My favorite type of editing is in-depth critique. I love to go over a piece, highlighting the things that a writer has done skillfully and correcting small mistakes, yes, but also suggesting edits and tweaks for style and voice. I can offer detailed commentary on what makes a piece FAIL to capture my attention or achieve its goal, and that is where the true value lies.
Because when you're submitting short stories to magazines or queries to editors, you're not (in most cases) going to get details on why you were rejected. You're just going to get a 'yea' or a 'no', and you may never know why. Wouldn't it be nice if there was someone who could look at your piece and steer you in the right direction?
Hi, my name is Dionne. I've judged several contests and book awards and worked as an editor for almost as long as I've worked as I believe you're looking for me? Contact me now for a free quote on editing services, and mention this blog post for a discount during the month of August.
