I am currently writing creative content for a Web site that focuses on recreational boating. Basically, I write descriptive technical navigation information on yacht harbors, rivers, water features and other nautical topics. Each piece is around 400 words and takes me about 30-45 minutes to do. I charge from 13 to 25 dollars per article, depending on complexity. I think I am charging way too little - I originally planned for it to equal out at about 30 dollars an hour, but by the time they hit me with revisions and proofreading issues, it gets down below my comfort level for the time invested... Does anyone have any idea what a "professional" web design firm would charge per hour to create content? I am on a 30-day renewing contract, and I want to adjust my prices with the market. I looked online, but couldn't find much. Thanks.
