I tried to set something up with that agency when I was in SLC and found the owner to be a difficult person to deal with. Ultimately it didn't work out as there was no one available after he put me through quite an ordeal screening me (and assuring me there were girls available). I get that agency owners have to be cautious and thorough, but he came off as flat out contemptuous. Some of his girls look good and have good reviews though. Just be forewarned.
