I’ve been working and scuba diving with Darin Duffin and Cari Duffin since 1999. This is the third iteration of their website and the first time we implemented WordPress. They are so happy how much easier it is to maintain their website in WordPress!
A unique design element of this site is that the main menu buttons link somewhere farther down on the home page. Their site is set up so that the home page offers just about everything you need to know as you scroll from the top to the bottom.
Switching to WordPress cut their website development costs to less than half what they were with a custom design HTML based website… primarily due to the fact that everything is a lot easier to implement now. Less time equals less cost.
