This question asks about finding a proofreader. It is currently cast as a shopping question (who should I use?), so I was going to edit it to make it more along the lines of "how can I find one / what should I consider?". But there are already several answers that this would invalidate.
Shopping questions are off-topic on SE (we missed this at the time somehow), but a question about finding and evaluating proofreaders is valuable for Writers. This particular question is a year and a half old and the asker hasn't been back. This question is also attracting self-promoting answers that I'd rather not keep -- not only are they promotion (feels like spam), but they are "too localized", unlikely to help future readers.
Should we close this question (and invite anybody who wants to ask the more-general question)? Edit it along the lines I suggested and delete answers about specific services? Something else?
