You may determine the Courtesans that sign by viewing their Official Page Profiles. You may check the Sheri’s Ranch Weekly Lineup http://www.sherisranch.com/lineup.aspx or Scheduled Ladies Coming Soon http://www.sherisranch.com/comingsoon.aspx. The Courtesans indicate the languages in which they are proficient on their profiles. Also, you may telephone the office and ask which Courtesans sign or email Madam Dena at dduff@sherisranch.com.
I briefly perused the Ladies Profiles and found that Violet indicates she signs: http://www.sherisranch.com/lady.aspx?id=643
