I realize this thread is old, but in case anyone has landed here asking the same question. A great many services have sprung up recently that offer very cheap "scientific English editing" services, but you will find that the quality of editing provided by these companies is poor.

A qualified scientific English editor should have a Ph Here is the definitive list of professional writing editing services near your location as rated by your neighborhood community. Want to see who made the cut?.

and academic publications, and ideally should be a native English speaker. This means that most qualified editors are professionals who live in the U.

, Canada, or Australia-- all countries with a high cost of living. What does this mean for you, the customer? Essentially, if you are paying less than 5 US cents/word for an individual editor, or less than 10 US cents/word for a company, you are not getting a qualified editor. There are few exceptions to this rule of thumb, I'm sorry to say, and I do understand that this price can be quite expensive if you are from a developing country.

However, you will not be saving money by hiring an unqualified editor-- instead, you will be wasting your money. One of the best ways to determine whether an editor is qualified is to ask for a list of their publications.

Even better is an editor with both academic publications and popular science books or articles. I can recommend a few services that I know provide high-quality scientific editing: JetPub Scientific Communications, Ruff Draft Writing, and BioEdit UK, as well as my own service, Carpe Diem Biomedical Writing and Editing (links below). There are many more out there, though-- look for clear, posted qualifications and a list of publications, and you should be able to find one with minimal difficulty.
