There are many books and a lot of information on the web about sign construction.
I don't think their is one book that covers all the answers about sign construction techniques.
If you don't have an experienced designer/fabricator on board you have to do your own research,research and more research.
I think many may have not replied because it's is funny question.
It's like saying"I want to be a brain surgeon"Can someone tell if there is a book that shows me how.
If you have a particular question I am sure there are many folks here that will help you out.
