CASTING!! need help!

This is a print screen from mine and Nora's conversation regarding casting for the main girl. We're really stuck! If anything... Nora or Julia may have to be the main girl.. I direct nora with the actual editing and filming.. I see myself as the Director, I bring the 'creativity' using camera angles and sound into the movie. but enough about me bigging myself up over being 'The Director' person :) hopefully we shall have all the filming done by the deadline... fingers crossed :)
