I don't really post on this site, just occasionally take a look at what's happening up on Winni, but figured I might have something useful to add here. I'm assuming your niece is getting married at Mountain View Grand? I got married there 2 years ago this September, beautiful spot, we loved it.
Anyway, we used a photographer named Kendall Bush, she frequently does weddings at MVG so she knows the place well and we really liked her, thought she was pretty reasonable as far as price as well. Her Website is below. Good luck to you/your niece in the search!
Take Care,
Mike
