I need to deliver my WP site in a zip file...

I had plans to deliver a cool WordPress site online, but due to various authentication and firewall and deadline reasons, I can't publish the site on the web. I have to deliver the content in a zip file to my audience.

Obviously this isn't ideal, but it's the interim plan. Can you help me figure out how to get my WP site in an offline zip file distribution?

I looked at this WP Static HTML Out plugin (http://wordpress.org/plugins/static-html-output-plugin/), which would work fine. However, the plugin is designed to transfer content to another domain. If you leave the base URL blank, the output doesn't quite work. I've read that if you do some search and replace with the output, it will work, but I get confused there.

Maybe there's a better solution? Or maybe you can help me understand what to search and replace with that output?
