Something to keep in mind, folks, is the distinction between a development edit and a copy edit. The copy edit tends to deal with hiccups in a completed ms draft. A development edit will usually start in the early creative stages -- sometimes even from conception -- with author and editor working in tandem as things move along ... and it will cost a lot more.
Whatever, any pro editor will advise you that proof-reading is a separate process that comes after final draft edit and is best handled by professionals who have, at this stage, not read earlier drafts of the work.
A good publisher will provide all these services as part of the deal. If you're aiming to go it alone and self-publish, though, be sure your bank account can stand a hefty hit.
Good luck. Neil
