Talk to the flower farm folks and see if there's something she can do as a "subcontractor" for them. Maybe planting seeds in starter trays or something, then selling the seedlings to them wholesale. Depends on how they run their operation, I guess. But that way she'd have her own business that she has to learn to manage instead of just being an employee. Getting paid by the piece rather than the hour teaches you a lot about how to work efficiently...
