Need Female Voices for a Children's Fantasy Animated Feature.

I am making an animated direct-to-DVD movie about a lonely little girl in foster care who on the day she is adopted finds a portal to the magical world of Genoma and befriends the lovable Mr. Wogglebug. Together they have an adventure rescuing the Enchanted Forest and rallying the residents of it to save it from a demented wizard. I have the main characters cast. The voices of the characters I still need are as follows: Sylvie's foster mother, Ellen Martin. She has a young and charming voice. Audition line: "You can call me Mom from now on." Sylvie's foster caregiver, Miss Clisby. She has a warm and soft and nurturing voice. Her audition line is "Sylvie is the most timid and shy child I have ever seen. Theodora, the Leader of the Pixies. She has a high and squeaky and cute voice: Audition line: "Pixie dust is all you need." Elysia the Fairy Queen Mother of the Elements. She has a motherly ethereal voice that is very warm and wise: "You, Sylvie Harnois are far more vital to this world and yours than you know."
