I'm Writing a story, and I am in need of OCs. Help me out here guys. Thanks :)

Hey guys!
I am writing a story about a nurse in a Children's Hospital who falls in love with a mural painter. She is put into the job after the last nurse mysteriously dissapeared. There was an alchemy accident on the 13th floor, nobody has been there in years, they are all too afraid. Anyway; I am in need of the following roles:
~Head Doctor (Male or female)
~At least two other nurses (Male and female)
~Children (Male and Female)
~Artist (Male)
And the nurse will be played by Charlotte, ElricLuv already asked me to include her. If anybody is interested, let me know.
Thanks! :)
