An experienced copywriter will charge you (if broken down by word) anywhere from 30 cents per word on up typically. Keyword being "experienced." I don't work that way. I look at what the client needs and then quote based on the project. In traditional copywriter, you might charge by page. But, what's a page on the Internet? A page could be 100 words, 1,000 words or 10,000 paragraphs.
