For starters, it may not be a good idea to charge a fee per word. That places emphasis on quantity over quality. Secondly, my personal opinion is that you must find out details regarding the company as it will help give you an idea on how much to charge without them rejecting the fee. Don't rush to charge a hefty fee just quite yet as you can increase your rate as you go on. Copywriters are still writers, and writers tend to have a hard time making money through freelance jobs. Coupled with Malaysia's not so fantastic attitude concerning small companies and spending large amounts of money for promotions, you'll have a very hard time surviving if you start by charging a high fee. Hope this helps. I'm a young copywriter trying to make some loose change on the side myself, and i found that the tricks mentioned above helped me get started. Have a nice day fellow copywriters.
