Couldn't agree more with using Jillian Mitchell and Elizabeth Lloyd, they are both excellent choices, super helpful, and very professional. Both great friends of mine.
I always feel that the most important thing when picking a photographer other than their body of work is their personality. Does it mesh with yours?
I can tell you that from a photographer's perspective it's super important to me that I attract the kind of clients that will mesh well with my outgoing and creative personality. And in the end, this will affect the outcome of the photos. Finding clients who are also super-positive, outgoing, and have a strong sense of self is really important to me because I know my style of photography thrives and is at it's best in that environment.
Hope this helps!
