I need to copy a hierarchy of pages multiple times.  Each copy of the hierarchy, including the skin, modules, and contents is to be identical, except for a single variable to be replaced throughout each hierarchy.  That variable is simply a few words of text found in the title, name , meta descriptions, keywords, and Text/HTML module content of each page within its respective hierarchy. 

For example, take the following hierarchy of pages:

"
HOMEPAGE - United States Information
-----California Information
----------California Business
----------California Construction
----------California Management
----------California Services
"

For the sake of clarity, these pages use one skin.  Each of the pages contain unique information, that differs from the other pages (ie: the textual content of "California Business" is different than the textual content of "California Construction").  However, the information is written generally, such that the same exact information is true, no matter what state name is placed in-line.  The goal, then, is to recreate the child and grandchild pages of the "HOMEPAGE" with entirely identical content, except for that the word "California" be changed to a different state name (such as Nebraska, New York, etc.) in each copy.  As I said before, the word "California" would need to be changed in the title, page name, meta description, and content of each page.  Other than that, the pages would be completely identical.

Please keep in mind that, in the actual project website, the variable word (or state name in the example above) is not the name of a state or anything otherwise available in any type of publicly accessible form.  In the actual project website, it is a list of locations that have been assembled by my employer.

There are probably several methods I could go about to accomplish my goal.  A list of options and a recommendation as to the simplest and easiest ones would be greatly appreciated.  Virtually anything would be faster than the method I have been using, copying each page one at a time, copying the text content of each module into dreamweaver, finding and replacing all instances of the variable word, copying and pasting the module back into the DNN module, and then copying and pasting over the variable word as it occurs throughout each page title and meta description.

In the actual project website, each parent page ("California Information" in the example) has approximately 30 child pages, and there are approximately 200 of those sets to be copied and edited. 

Would be great if I could just Copy all the pages and subpages, filling in the name of each "state" only once per set.

Thank you for reading my wall of text.
