"How much should I charge? ask writers and editors." The answer: That depends (among other things) on
how good, how fast, and how reliable you are ("Cost. Quality. Speed. Pick any two.")
how rare or specialized your set of skills (how valued the hairdresser who knows just how to do your hair)
how deep or specialized your knowledge of the subject (and audience)
what the market will bear, which varies regionally and by industry (book publishing is dirt cheap)
how much the client can afford
how easy you are to work with.
You can learn a great deal from the many following pieces (and books) on how much to charge, and whether to charge by the project, by the hour or day, or by the word or page?

Even for articles of the same length say, 1,000 words some outlets pay as little as $100 and others pay as much as $2,000 (or more)....Three factors will affect how much you can or should charge: Your budget, how good you are at what you do/the price you can fetch, and how much time you have."

Organizations may not set or recommend rates (they can get in trouble for price-fixing), but many (such as EFA and ASJA) do member surveys of rates charged, fees earned, how difficult particular clients were (this can save you hours of grief, particularly regarding the "hassle factor" -- e.g., editors who don't know what they want, change their minds, or who must run everything through a committee which has a preconceived idea what the writer should be saying) and how slow a client is to pay).
