Rates vary according to the project's complexity, the timeframe, and how much other work I am contracted to do at the time, but it ranges from $45. to $70. per hour. This rate is a bit below average for editors with similar training and experience (note the average rates paid to writers/editors across Canada from the website, http://www.writers.ca/whattopay.htm), but I love my work, and would rather charge a bit less and be hired a bit more. I offer a reduced rate of $40. per hour for students and non-profits.

New clients are sometimes surprised by the cost of a professional edit. I typically assure them that clients with similar concerns come to believe it was money very well spent when we are finished. Secondly, after hearing horror stories of work not ever returned, or not completed according to the agreed terms, or needing to be redone, I am reminded of Red Adair's classic line: "If you think it is expensive to hire a a professional to do the job, wait until you hire an amateur..."

Three main style guides–

  1. Chicago Manual of Style (also known as Turabian style, and perhaps the most popular)
  2. American Psychology Association (APA)
  3. Modern Language Association (MLA)
Many variations are based on these, but the most important aspect for any individual piece of work is consistency. A style guide can be as basic as noting such issues as whether a serial (aka Oxford) comma is used; which words are regularly capitalized; whether British/Canadian, or American spelling is preferred (unless otherwise instructed, my default dictionary is the Oxford Canadian Dictionary); how headings and subheadings are presented/formatted; and/or the correct spelling and capitalization of any terms peculiar to your field, to name a few main items.
Please let me know if you need a guide suitable for others’ use when you send the sample materials so I can estimate a reasonable fee to prepare it for “public” consumption. Some printers request one, for example, or your project might be the first in a series, in which case a style guide will save editing time for subsequent pieces.
