Move Site and subsites to new Web application

Hi

I have a SharePoint Site used for Sure Step.  Each Sure Step project is a subsite.  This Sure Step site has its own set of permissions to the rest of the site collection.  I want to move the Sure Step site, related contents and subsites to its own web application.

What is the best way to move this Site and all of its contents including sub sites to a new web application?

Thanks

Marc Collins
