What do you think of twitter pitch type contests? The current one is #revpit where you submit to three editors a query letter and five pages and answer a few questions.
They go through them, make anon comments about the query letter and pages. They can ask for partials and fulls and end up picking one to work with for a month.
What do you think about freelance editors overall?
I think freelance editors can be terrific, and some of them aren't worth much at all.
I have no idea how to find out which is which short of seeing what they say about your work. Except of course, the best editors often tell you things about your work that you're not all that eager to hear. As in you have six plot holes, and the tension drops to zero in chapter fourteen.
I've had very mixed results when sending writers to freelance editors but there's no way to know if that's cause the editor isn't very good or the writer didn't do what the editor suggested.
I recently heard back from a writer whose full I'd read and thought needed a lot of work. She told me she was just going to self-publish it instead of revising. I'm pretty sure editors have had that same thing happen.
As for Twitter pitch contests, it's not like they'll hurt you. And maybe they'll open a door for you. And maybe one of the editors will tell you your tension drops to zero in chapter 14, and you'll actually hear her and plan to revise.
In other words, there's no reason not to participate in these kinds of things. If it helps, great. If you think the advice you're getting is dreck, at least sit on it for a month before ignoring it.
