I just got this posted on my publishing site…
Self Published Business Book Contest
The 2006 Small Biz Games (http://smallbizgames.com) Self Published Business Book Contest is open to all English-language self-published books on any topic relevant to micro small business owners and home based entrepreneurs for which the authors have paid the full cost of publication, or the cost of printing has been paid for by a grant or as part of a prize. Identical topics for the Business Ebook category.
Just so you catch that last part, there is a separate award for business e-books, which should be of interest to the Internet Marketing crowd.
More information, and a link to the book prize page (not yet linked from the smallbizgames.com main page) are here.
