On the recommendation of Eric Cheng and others here at Wetpixel, I recently established a website with Smugmug.com to house my best uw photos. Although their standard setup looked a lot more professional than my old website, I decided to use the services of a guy in Michigan who customizes Smugmug websites, and for a VERY reasonable price, he (with my input) established a new "look" for my website, with a nifty slide- show on the home page and some other cool features: http://www.underwaterreflections.com/
One reason I chose Smugmug was that several people have asked how they could purchase prints of my photos, and Smugmug allows online photo sales (I'm donating all proceeds to charity) if you upgrade to their "Pro" program, which costs $150/year.
If you are interested in establishing a photo website of your own with Smugmug, go to www.smugmug.com and check out the cool options they have available! If you decide to sign up, you can enter my referral code (1C8m55WBF6RMo) or Eric's if you prefer (iKbVLA6djb4uE) in the "Referred by" space and you'll save $5 on your subscription.
After you get your site up and running, if you want help customizing it, I highly recommend the fellow I used: Jerry Roek ( jerryroek@comcast.net). He was extremely reasonably priced (he typically only charges $200-$400 to set up a custom Smugmug site), is easy to work with (we did it all by e-mail and a couple of phone calls!), and he did (IMHO) an outstanding job!
I would welcome any feedback or suggestions regarding the site!
