Flashmob dancers for wedding proposal

I like to do my wedding proposal framed by a surprising flashmob dance to the song "marry you" by Bruno Mars (as could be seen in examples on youtube). Best date for this would be Tuesday 11th of March 2014 in the evening when we are staying in Singapore (Marina Bay Sands). As we are from Europe and I cannot asist in the preparation I need a reliable person who organizes and takes care of this short event. Thank you in advance, Daniel
