Mary Noone of Shutter by the Sea. She's based in Cohasset, but recently moved there from the South End. Her company was formerly known as Shutter in the City (when she was in South End). Here's a link:
Also, Fredricksen Photography out of Marshfield. Husband and wife team. Nichole, the wife, recently took photos of my two daughters and they came out beautifully. Here's a link to their site:

I listed Mary Noone first simply because she's lived in the South End, and probably would have no trouble coming to you. Hope this helps!
