Eproofed - Information Architecture document

To-day I have finished my first Information Architecture document for the prototype of my site Eproofed.com. This site will be used to support my business of editing and proofreading documents, brochures, advertisements, journal articles and even books.
From my search of other sites on the Internet most of the businesses are groups which specialize in particular subject areas such as natural sciences, pure science, engineering and technology. Most are international groups with a few Australian based groups.
I have found that learning about Information Architecture is a really good area to work through and to relate to my work with new clients.!
