Well, I must say that I was impressed. There are a few things I would make adjustments to, however.

He turned his glance to his oldest child. Eleanor, like her famous namesake, was a very intelligent and strikingly beautiful woman. She used her mind and body to equal effectiveness in improving the revenue stream. It was her ideas that had brought the family business into the twenty-first century. Instead of just providing the highest quality slaves to the buyer, they also produced DVD’s, streaming video, and pay per view satellite programs to those who were unable to afford a slave made to order.
This was a good paragraph. I would change the highlighted "also" to a "now". that is my only stylistic complaint here.
