"I wanted to thank you for all your work.  The office looks better than any of us could have imagined, and the morale in the office definitely shows that as well.  It was a pleasure working with you, and I can't wait to see what you create in the future."

"Do the right thing and hire DesignX because Allison, the owner, not only saved our place and image, but took our concept to the next level.  Honestly, I couldn't have imaged such an amazing design.  We will definitely be working with DesignX on future projects."
