1) Take the EXACT same design located at [[login to view URL]][1]
2) Create a 'mirror' of the site using Joomla
3) Publish the mirror design in the sub-directory [[login to view URL]][2]
4) Profit!
Special Note: You DON'T need to recreate any content or pages - just a single template page - WE want the original website left alone on the root of the server - just the Joomla published on the sub-folder. Easy!
