Create The Most Neatest, Comprehensive Prewires In The Industry, What Would Be Suggested?

We have been in the business for 22 years and have specialized in retrofit installs only. We have shifted into some very high end installs pre construction. I was hoping I could get some support on language, design,tools that would be helpful in performing at the highest level of installing protocol that if money was not a problem and we could create the most neatest, comprehensive prewires in the industry what would be suggested. For an example a 20,000 sq feet home, 2 stories with no basement( in Florida) with an alarm, fire system, CCTV, AV systems, where can I find books as far as engineering, the entire system properly?or if anyone wants to share setup protocol they use.

Syed, your request might be a bit too broad for anyone to reasonably fulfill within a forum post.
