Do you look for different people to undertake different levels of edit?
The simple answer is… maybe.
Some editors edit at all levels and proofread as well. Some editors don’t proofread. Some editors only copy edit.
Most people advertising as proofreaders don’t edit, yet. They may be happy with proofreading and not want to take on editing. But, then again, they might be studying to be an editor.
Some editors and proofreaders specialise in distinct genres, and will normally advertise their specialities. Others accept a wider range of genres.
Selecting the perfect person to work with
So, it really depends on the individual. Ask questions and see if your book is right for them and you are a good fit. The more experience they have with your genre, the more they bring to the editorial process. Choose carefully and don’t go for the cheapest – unless they are also the perfect match. The quality of your final work should be the guiding principle for selecting the best editor/proofreader. Don’t scrimp on a few pennies and regret the decision later.
If you have rapport and they ‘get’ you, your book and your style of writing, then you’re off to a great start. If the finished product is your overriding concern, don’t be afraid to interview and select rather than just hiring the first or cheapest person.
No, not all editors are equal, not all are up to the task of nurturing your work to bring out the best in it.
