It's a Lulu

I have created and published a textbook using the electronic service available at Lulu.  Lulu's model is to allow writers to upload their books, and it lets each writer choose her or his price point.  Lulu takes a fixed percentage for each print copy purchased, binds and ships the book to buyers, and generally handles all of the e-merchant fulfillment tasks.  I am trying Lulu with a textbook I have written, entitled Electronic Marketing. The URL is:

I see some drawbacks of the Lulu model in comparison to using a traditional publisher: 

1. The quality of the printed product is not up to the usual book standards.
   
2. No salespeople are pushing the book across the country and around the world.
   
3. Publishers frequently arrange for reviewers to read and correct texts. 
   
4. Publishers' sales forces can gather feedback useful in content creation. 
5. Publishers offer technical help including indexing, formatting, art work, etc.

I am thinking through ways of overcoming these drawbacks, while enjoying the benefits of the Lulu model.  These are: 

1. The author can keep the price low for the book, thus benefiting students.
   
2. In spite of the above point, the author can earn more per sale than is traditional.
   
3. The author can revise the text on any schedule, thus adding to flexibility.
   

I am not sure how this will come out, but so far I am quite impressed with Lulu.
