One of my friends just went to the Mac counter the day of her bridals and had them do it for free to see if she liked it.  That way she had free make-up done for her bridals.  She said it only cost around $50 to have them come do it the day of her wedding.  I don't know what they have one in park city however.  She also did a spray tan but she went to a place that does the air brushing tan (where someone sprays it on you).  It was pretty inexpensive as well.  She did a trial run a couple weeks before her wedding to make sure it looked alright.  Good Luck!
