First, welcome.
Second, I was a long time hobbyist in other places, but was new to Atlanta. Some fellows here helped me greatly, especially xy23, so I will in turn work to offer you some counsel.
Third, I highly recommend getting a P411 account. It verifies you and once you build up some okays you are good to go with most agencies and indies. I strongly recommend this route to you.
Forth, some girl recommendations. Ginger Taylor, Regan, and others
Prior posters have mentioned Ginger Taylor. I have not booked her myself (yet) so on that basis I cannot fully recommend her. Given the number of reviews she has received, the feedback in those many reviews, and the posts by gentlemen here whose opinion that I value, all that cannot be wrong. Her record has to speak for itself.
Now, I have met her personally at a meet & greet function. I greatly enjoyed my conversation with her. She is a red head with a certain alluring naughty twinkle in her eyes. I admit it, I was tempted to whisper in her ear if she would consider leaving the party for awhile to do something naughty. Alas, me being a chicken shit, or perhaps a gentleman, I did not do so. I might have gotten slapped for breaking the rules of the party, so perhaps well I did not. I don't mention this in disrespect to Ginger. She just has a subtle "hey I am up to it if your are" kind of a look to her. To sum it, I have not booked her so I cannot fully recommend her. I can say that she impresses me as a great time.
Ok, I have seen Regan at JFL and so recommend her. Up for most anything. pleasant, good looking, and the word "no, I don't do that" is not in her vocabulary. In fact, she will up ante you by saying "yeah. lets do that". OK, she is working and this is what she does. The key, she makes you feel valued as her partner and works to make you happy. She has a radar for being treated with respect, and she returns it in how she becomes your partner.
Lastly, Gold Club responded to you. They took a chance on me as a newbie. I appreciate that. I have seen Olivia there and recommend her. Work with them, choose the girl you like, and they can get you where you wish to go.
Another possibility among many, Exotic Flavors. Great to do business with and the girls aim to please. I have seen Kassie and highly recommend her.
What is omitted in your post is what type of girl that YOU like. Having that would help me narrows down some recommendations. All the ladies I mentioned above are excellent.
