Does this item have any commercial value?

If you've ever purchased a WSO I would greatly appreciate your feedback.

I have a document that I've created and periodically updated that I deliver to my offline clients for free as part of the package I offer. It's called 'The Manual'.

To make a long story short, I research and create web marketing strategies for small businesses in my area. Typical job is around $2k. Part of the deliverable is a multi-page document outlining the web strategy I recommend the implement in order for their business to be successful. This document contains a lot of industry jargon and acronyms and the like, and it's not practical to try to explain everything in the web strategy document as it's more of a presentation piece than anything, so I offer 'The Manual' as an auxiliary piece to help explain the concepts of email marketing, link building, SEO, etc. that are referenced in the strategy doc.

Essentially, The Manual has grown into a textbook of sorts that is now over 100 pages long. It is full of great information that covers in depth pretty much every aspect of Internet Marketing you can think of (much of which has little to no relevancy to my clients' endeavors, but I include it anyway). I update it periodically as new information becomes known and new techniques are developed.

I provide this piece, as well as subsequent updates free of charge to my clients. But lately, I'm beginning to wonder if something like this would be of value to some of the less experienced people that come to the Warrior Forum seeking advice and information.

I struggle with this because this isn't the typical 'Follow this blueprint to make $1432 a week' hyped up product ubiquitous in the WSO section today. The truth is, this is a wealth of knowledge accumulated over a period of time that, if consumed and absorbed properly with the correct mindset and perspective, could educate the reader to the point that they are able to develop and implement their own strategy with the fundamentals they gain from The Manual.

My question is how much value does an item have that doesn't follow the formula of a traditional, hyped up moneymaker? In all reality, this is information that could be consumed for free - provided that a person was willing to spend the dozens of hours reading forums, blogs, and other publications in order to obtain it.

Any feedback about the value of an item like this, as well as what one would likely be willing to pay for such information, would be greatly appreciated.
