"I'm writing to say "thank you" for all you did to develop our beautiful new web site, which is getting rave reviews. I'm guessing this wasn't the simplest site you've ever developed because working with a committee usually isn't. And of course we wanted the site to be rich with information, which it certainly is. The website itself is aesthetically attractive and as important, very easy to navigate. But my real thank you comes because anything we asked for was always, "no problem," and we asked for a lot. On top of all that, you had suggestions for additions and improvements that we didn't even think of. You made more work for yourself and did it happily. It was apparent that you wanted the site to be perfect as we did. You became an important member of the team and I came to value your professional expertise. I only wish that every major project we undertake like this one comes with "no problem!"
