The first commercial website I ever built. It's for a dentist in Billerica.
Interestingly, the technical parts were relatively easy.
It was much harder to deal with the requirements - the dentist knew he wanted a website, but didn't know what he wanted other than that.
And it was hard to deal with the content.
I found that the only way I could make any real progress was to make almost all of the choices myself, then present them to the dentist for approval.
It was an enlightening task.
