If anyone is looking for a calligrapher in the Phoenix area, I would highly recommend Pauline Abello from Inviting Ideas (
http://invitingideas.weebly.com/index.html).
I had her address the inner and outer envelopes of my wedding invitations and could not be happier with her work. I cried when I picked them up because they are THAT beautiful! She was very reasonable in pricing, she actually made a custom ink color to match my invitations, and she had them all done in a week!
I know a lot of brides don't have the calligraphy done anymore, especially with all the technology now (it's so easy to run it through your printer at home), but I have to say, having them done absolutely made my invitations. It added a touch of elegance that isn't seen so much anymore. I know that my guests will be in awe when they receive my beautiful invitations in the mail!
