Inverting, regulating charge pumps

I'm working with 24V but need to generate +-10V or +-15V rails centered around ground to drive some differential line drivers. I know enough about charge pumps to know that this is a good application for one, but I don't know enough to select one. Any IC recommendations to provide an inverted regulated rail and a noninverted regulated rail? I need about 20mA max from each rail.
