As far as I know Joanna reps herself. You could probably find her on myspace. Bree's agent is Chris at Foxxx Modeling. As far as I know, neither girl is a flake (they've never flaked on me) but I don't think either girl actually lives in LA so you've got to be able to coordinate their schedules. And I don't know if Bree's contract with Adam & Eve would be a conflict.
