Wedding proposal photographer

I am going to be in Venice on Tuesday October 12th with my girlfriend and am planning on proposing to her. As you can see this is very short notice but I am looking any and everywhere for a photographer that is available and willing to accept this job. I am simply looking for someone that can photograph the proposal as well as edit the pictures for us. I have looked into some locations for the proposal but would love to hear any input from the photographer if they have any ideas for a good spot.
