Sorry in advance that it isn't completely Drupal related. Most of my experience is with Drupal, and I've got none with Joomla. I'm hoping to find some one who is experienced in doing advanced themeing in drupal (not using panels for layout purposes, uses contenttemplate, etc) who also knows some stuff about Joomla themeing/templating/whatever they use for a term.
I'm not rich, but I'd love to buy you dinner in exchange for you simply showing me the process you take to create a very very rudimentary template/theme/whatever in joomla. Afterwards we can chat a bunch about drupal stuff. Maybe i know somethign you don't, maybe I'll just keep learning.
Anyways, opportunity for a free dinner and to help a fellow portlander out. Also don't worry, I have no intentions of moving over to the dark side, I'm a drupal bandito! I just figure I gotta know the enemy.

Artisteer
I know it's not necessarily the best thing if you are trying to learn theming, but Artisteer will create Joomla as well as Drupal templates and themes.

I'm trying to learn the skills myself to be more employable and diverse in my skill sets. Paying some one else just doesn't fly unfortunately!

Artisteer is a themeing software
not a paid service. It actually works great to build a core theme from, but you may run into modules that don't play nice. I have found the themes fairly easy to perform surgery on.

That was more along what I was thinking. Also, the Artisteer trial allows you to fully create a theme and export it and the only difference I noted between the trial and purchased software is that the trial puts watermarks on the images. Still, a developer type license, as of last May, was only $130.
