No I don't, but would be interested on anything you can report here. Articles written in the US press recently indicate that Atlanta is a mecca for prostitution, but this is probably total BS.
What I can tell you is that prostitution is illegal there, and almost certainly very expensive. Probably the safest option would be to find escorts who will come to your hotel, either from the Yellow Pages, or, better, from the Internet. You might start at

There is an agency called Chocolate Fantasy Girls that seems to have had an online presence for a few years and appears to be service oriented.
As you probably know, Atlanta is a predominantly African American city, so whatever ladies you meet will probably reflect that.
At the risk of sounding patronizing, and knowing nothing of your schedule or budget, Atlanta is the main hub for Delta airlines and you may be able to get a reasonable priced flight from there to Santo Domingo for a couple of nights, where the mongering possibilities are much better value for money, much better quality, and, above all, 100% legal.
