For my daughter's wedding last September and my daughter-in-law's two weeks ago, we use a make-up artist that was recommended to us by another bride. Her name is Laura Mushenheim and she did both bridal parties and the mothers. Everyone was very happy with their makeup. She is a licensed Esthetician. She is from the South Hills but will travel to your site.
Her no. is 412-480-4643 email: lauramar@comcast.net
Hope this helps those of you looking for a reasonably priced makeup artist.
