There is limited information on the Sound Wisdom site, so I did a some googling and found the parent company, Nori Media Group. One of their other companies, Destiny Image, claims to be a traditional publisher. Be very wary of this company. On the Destiny Image website it states:
What is the cost of publishing?
This can often be a frustrating topic for new authors, as there is no set number that will be true for every book. Each book is unique, so costs will vary. When working with brand new authors who have not yet established a strong platform, we typically require a large pre-purchase of books (anywhere from 1,000 to 3,000 books–depending upon the subject matter of the book). This amount will be stipulated in the contract that is signed. These books will be sold to the author at a highly discounted rate, and will simply serve as a sign of investment and commitment on the part of the author.
The task of publishing and marketing a book is a partnership between a publisher and an author, and this partnership will require commitment to the project. Typing “The End” is only the beginning. Be prepared to help develop, promote, and market your book while we work to do the same!
Do not sign a contract that asks you to buy several thousand copies of your own book unless you know beforehand that you will need these books to sell at the end of lectures/presentations, and you are absolutely certain that you can sell every single copy. Even so, this is not a very good publishing model and not one I would recommend.
