The ThemeZilla team has been one of the most consistent and trusted providers of premium WordPress themes basically since the beginning of time. Their collection speaks for itself, they have a design for just about everything, and a great collection for creatives in need of a portfolio site. Of course, what would you expect from the team that brought us Dunked?
While many of their themes are built for creatives and photographers, they can be adapted for use in just about any industry. Themezilla themes don't come with a bunch of extras, just a clean layout, nice blog and page template, and beautiful code.
