Something that's come to mind recently: KBoards, in its Yellow Pages, doesn't distinguish between the different stages of editing a work. I suspect it's for that reason that over the past couple of years I've been sent works that seem to me to be first drafts. Now, far be it from me to discourage people from sending me jobs, but a copyeditor/proofreader is most useful when working on a manuscript at a later stage. Think of it as the paint job on a car. You wouldn't send a car out on the road unpainted, but neither do you send it out to be painted before you have all the parts assembled into a working automobile.
Just something to keep in mind...
