It is in process now. Basically, it is a WP Responsive theme style sheet with separate footer,header, navbar, and body php files.
Originally, it was thought there would be no blogging but now there will be some articles. So, would you leave it as a static php file and add content as needed which would then not have the benefit of tags, automatic adding to xml sitemap, dates, authorship, pinging, etc.
If there were a way as a static php site to do the above (include the date/url format like wp, content tags,adding to sitemap automatically, author, etc.) I think I would leave it as is. It will be for a loan site, if it makes a difference.
It appears I answered my own question.
