Copywriting is, no surprise, a business, so if you want to be successful, you must treat it as a business.
My copywriting e-course teaches you how to build your copywriting business from the ground up. Full details here: "Writing Words that Sell: Freelance Copywriting".
The major benefit of the course is that as you work through the course, you're working on your business, creating all the marketing tools and contacts that you need for a successful business.
Copywriters' job board
In 2006 I'll be extending the course to create a freelance copywriters' cooperative, with a jobs' board, so that course alumni can spend more time writing and less time marketing. This means that once you've completed the course, you know that you'll have all the work you can handle. Membership in the copywriters' cooperative will be limited to copywriters who have completed the course.
