In your AN you said you were going to do something different with Albus.
There is a story on fanfiction.net that is simular. Major differance, your girls that are earning him money are not slaves. The3 story shopuld you decide to look it up is called The Harem Wars, a very detail oriented fic.

Good Morning:
Actually, I've read Harem Wars, and that Albus is very different from what I'm going for in this story, although Radaslab's version is very interesting.
