Massage DVD set Sales Letter

I have a set of 3 DVDs which deal with Head Massage, Facial Massage and Full Body Massage and I want to package them a a set, which will be a very high quality product. I am looking for a Sales Letter which will reflect the quality of the products. I abhor hype in any form and things like multiple exclamation marks for example. I think the letter should run to a couple of pages and should cover Benefits, Benefits and Benefits. I like to see problem outlined, then how the product solves the problem. I am not in a hurry here, so a good result is better than something cheap-looking that has been rushed out too quickly. If needed, I may be able to help out with graphics, although I think words sell, not pictures.
