Why do prices for editing vary so widely among companies?

As with many services, “editing” is difficult to standardize or quantify, and quality can vary widely among companies. Many large editing agencies provide what amounts to simply proofreading and copy-editing, without considering the content of the manuscript or the presentation of the data and ideas. My approach is to provide full-service professional editing, which means that your entire document will be checked carefully for grammar, punctuation, and spelling; in addition, I will ensure that the style is clear, the writing is crisp, and the story flows smoothly and is internally consistent. In short, I provide the best editing at the best price.
