I was looking to surprise a friend for her birthday by sending someone in costume to her workplace. I didn't have all of the particulars down, but David replied and was extremely helpful. After we settled on a character, David was responsive to my requests regarding how he would perform. He was very communicative throughout the whole process and, per my request, he was even able to procure a dead fish (a whole one, with a face and everything) as a special gift for a very special birthday girl. Needless to say, if I were independently wealthy I would pay David to do equally awesome things all the time.
