I should think it would make a good report, or even 'free report'. There's honestly not that much to it... and most of which you can learn from the freelancing sites (such as elance, freelance work exchange, etc).
So many people are looking to hire writers right now that it's a great thing to get into for those that are looking for part-time work online, but dont have a lot of business knowledge or experience. Even just for extra money.
By the way, if your friend is for hire for small jobs, feel free to have her contact me. I look for writers on particular topics from time to time, and may be able to send some work her way.
