We use templates from RocketTheme for the Joomla sites we build for our clients (we have a membership that lets us do so). Use the following link to go to their site and check them out and see which template you like the most for your site. Then, let us know which one it is and we'll customize it for you.
One note - the good folks at RocketTheme have their demo templates jam packed with something in every module position. So don't worry if you think they all look really busy or cluttered. Yours doesn't have to be that full. Just look for the colors and basic graphics that you like the best.
Keep in mind too, that each template has a number of different color schemes with it. You can view them under the "Features > Style Variations" link in each template.
To view the different templates, just use the "month/template name" drop-down at the top of the page at http://demo.rockettheme.com
