Simple logo needed for School Bookseller web site

Schoolhouse Publishing Co.

You can see my existing logo at http://www.TeacherTrainingBooks.Com. I am going to pay someone here on 99designs to redo the web site to make it look more profesional. Before I do that though, I want a new logo that is nice and simple. I sell books to large school districts that are used to train teachers how to teach. My existing logo is pretty cheesy and it looks un-professional. Also, my existing logo says "Schoolhouse Educational Publishing Co." and I want to drop the word "Educational" from the logo thus making it shorter and more concise.

My target market would be large school districts all across America. My customers are not the teachers themselves but rather the individuals in the professional development departments.

I really don't have any pre-conceived notions of how this logo should look. On a scale of 1-10, I'm a 1 in the creative department. That's why I'm paying you. I think the more simple it is the better it would be. My company name (Schoolhouse Publishing Co.) doesn't necessarily have to be in the logo. My only hard requirement is that you do not use any clip-art. All work submitted must be original and you must be willing to give me full rights to the finished product.
