ADVICE PLEASE

I am about to embark on a major writing project and would appreciate your advice please. I intend to write a book consisting of a list of all the words used in the English language. The words will not be in alphabetical order and there will not be a definition of the words either. It will be a random list such as:

The and garden notwithstanding hoover fortnightly eaten quarter simultaneously ... and so on.

So far I have written about 113 pages and it is hoped the book will be completed in about six months time. I have a team of six people in my employ working on this.

I guarantee that there will be no repetition of the words and that they will all be spelled correctly both in English and American - e.g. humour/humor.

The book would be a great pastime when travelling on a bus or train, or when you can't sleep in bed and have nothing better to do, or when relaxing in a hot bath. 

The intention is that you'll think of a word and time yourself as to how quickly you can find it. Hence the absence of alphabetical order. Of course if you're in the bath at the time you'll need a water-proof watch (not supplied with the book).

Another use would be to check if you've spelled certain words correctly. For example you could look for the word: Onomatopoeia, but because the book is not in alphabetical order it will be great fun trying to find the word, and in searching for it, you'll discover other words you did not know that you did not know!

A further fun use is to play a game with your spouse or friend. You can think of a word and your spouse or friend has to find it within a set time limit. 

I have three publishers interested in this unique venture in the history of publications.

What I'd like your advice on please is whether you would find such a book useful and how many copies you are likely to purchase. They make a great Christmas gift for family and friends; and are a good conversation starter to break the ice at parties. Please also give me an idea of the price you would be willing to pay for this book.

The information would be very helpful in estimating the number of first print run. One publisher suggested 500,000 copies but I am not sure if this will be enough.

Thank you.
