If you use Dreamweaver and you have $100, I recommend looking at Media 65’s Joomla! Tool Kit. I bought this to help me convert a Magento template that I purchased into a Joomla! template. Funny thing is, the videos that came with the extension were just as valuable as the extension itself.
Proof…http://www.m65.net/demovideo/jtk3xdemo.h… amazingly simple.
P.S. I do not work for http://www.m65.net. They do not know me other than as a user account in their bulletin board. This software really helps me to do what this question asks, so I posted. Good luck.
