Dear Potential Client:
After reading your post, I am very interested in working with you in completing the projects you indicated. I am a published author, having written for a number of clients; most of my material has been non-fiction and developed for various educational genre. One of the most intriguing aspects of your proposal is well aligned with my abilities and interests, as I enjoy working with information and redeveloping it to help increase public awareness or educate readers, regardless of the topic.
I will be more than happy to send you samples of my work (those that are available on my harddrive; I can also send you copies of the front covers of some of the books I have written, etc.) as I know all too well that it is important for a client and a writer to form a "perfect fit," and have an appropriate 'meeting of the minds,' so to speak. If you should be interesting, let me know. I will be interested in discussing these projects with you.
