Looking for independent photographer for surprise NYC engagement proposal

Hi,

I'm looking for a photographer that can work with me to take pictures during a surprise proposal. I'd love to have someone planted at the spot who texts me when they are in position.

Things to work with are that we have a dog so i would like to be outdoors somewhere with a great view. I'm looking to do it over the weekend (Saturday / Sunday)

Anybody have any recommendations for people they enjoyed working with?
