Phlebotomy Training Center
I was surprised to find out that you can get a phlebotomist's certificate online...even more suprised that there are already several sites out there that do the exact same thing!
For this client, they wanted a simple way of conducting classes online, and I couldn't think of a better platform than Moodle. Moodle made it extremely simple for this site to conduct their assignments and tests, and even had a payment module available for charging customers. It was a very, VERY simple looking site, completely by accident: I had the simple site with a basic template ready just so I could show them functionality and see what they wanted added, but when I asked the client how they wanted me to change the look, I was told, "Don't change anything." Admittedly, sometimes, the simplest site is the most effective (anybody heard about this Craigslist site?), but, I expected them to request SOMEthing more!
