Casting 'The Receptionist' - My Actors

I need three actors for my opening sequence, and I have chosen to cast teachers and students from my college to appear in the film, and to give them 'fake' actor's names.

Louise (the Drama teacher) will play Liz - the film's central protagonist (in the titles her 'actor' name is Lucy Blackstone).

Alice (a student) will play Louise's daughter (in the titles her 'actor' name is Alice Crow). 

Alex (the Film teacher) will play the Boss (in the titles his 'actor' name is Robert Nicholls).
