Hi guys!

It's fairly easy to just give them a call, say you're new and interested in working for them and see how it goes. If the agency is taking more than $100 per booking, look elsewhere. You'll be expected to pay your driver 40-50 on top of that, unless they will set you up with incall. Pick up some books from Amazon. Amanda Brooke has a good guide that will walk you through some things.

Thanks a bunch. I was just wondering, how do you know if agencies will actually be honest about how much of the cut they'll be taking?

Several of the Atlanta agencies have good reputations and are well established, some for years. If you have done the research already you should already know who they are.  
If you want to interview, you don't interview with the employees. Go directly to the source.  

Few things:
I am pretty sure you can find a more experienced lady to mentor you and give you the right advice, while the agency option is a great way to start until you know the ropes remember that nothing is 100% percent guaranteed in life. Even some agencies that pride themselves of perfectly screening the clients have other issues on the side (taxes, crazy owners etc.) so once again, do not think that they know it all or are almighty. Another option for you is an assistant, somebody competent, experienced and willing to take you under her wing. Usually they have worked as companions before so they know exactly the different scenarios, how to talk to clients how to keep you safe and explain you everything etc.. without the hefty commission the agencies charge (60% for you, 40% for them in most cases). Nonetheless, If you do end up talking to agencies, NEVER give them your real information, always be cautions on what you disclose, be trustworthy but always keep your guard up. I am sure there are excellent agencies out there but I would do tons of research before making my final choice, ask as many questions as you can, read reviews, ask them to meet the girls, research if they are incorporated, ask about their incalls, owners, past issues, places where they advertise, etc..  
Knowledge is power and even more when your safety is at stake..

Thank you so much! This was definitely helpful. Finding a mentor would be ideal but I definitely don't know how to go about doing that without just meeting the girls from the agency. As you said, everyone has to keep their guard up. Any advice there?

Jada:
I am glad I was able to spark your curiosity, while agencies need to ensure that you are not under the legal age, they don't need the extra details about you (address, real name, etc). If you present ID, cover your real name and address with black tape so only the DOB is showing as well as your picture. Maybe I am just a bit over the top, but I am just terrified of all the scary things that agencies have done to girls that decide to leave them. On the flip side, agencies are also careful of girls that steal from them, (not only clients but money) so always act in good faith and show impeccable character so you don't bring the worst out of the owners.  Treat the opportunity as a real job, take the best out of it and make your choice. Everyone has the right to leave, be independent or just move on, but honesty should prevail in all the cases. In my case, I started with an agency, and I am grateful for the opportunity, the learning experience and so forth. I never burned any bridges with them however, it was an eye opener for me to know that I was ready to become independent and be responsible for my choices. Nobody can tell you what is right for you but we could just give you guidance and advice so you can be safe. Sometimes even clients can suggest a mentor or an assistant that they have dealt with in the past, you can always inquire with any client you feel would be willing to refer you to one. Nevertheless, never comprise your safety under any circumstances no matter how great the opportunity sounds.

When calling the agency and inquiring about working for them, how do you know that they won't assume you're law enforcement or that you're serious. I have an agency in mind. I sent an email (no pictures) but did not hear back from them. I'm nervous about calling them now since they did not even respond to the email. Advice here?

Thank you again. This was also very very helpful.

A personal assistant who was a provider is an option? so you could be independent, feel safe and still not worry about agencies taking large fees.
