You want to move, YOU pay all the expenses. Nobody is going to help you. You will need sufficient funds for: transportation to Atlanta, temporary accommodations (e.g. hotel) while you look for apartment; 3 months rent in advance (security deposit, first & last month's rent); utility turn-on fees & deposits; furniture & furnishings for the apartment; local transportation; health insurance; appropriate attire for job hunting, work, climate, etc.; food & everything else you need until you are earning enough to pay for it all.
Expect rent & utilities (electric, cable, internet, phone) to run $2000/month for a very modest 1 bedroom apartment, and it can run more.
You will need proof of employment with earnings of at least 3 times monthly rent to apply for an apartment. IF you have a good job lined up before you arrive, you might be able to get by with $10,000-15,000 to set yourself up. Without a job, you could have twice that much & still have trouble. If you want a car, you might find a used car in good condition for around $10,000, and auto insurance can run $1000/month if you are under 25. You have NO credit, so pay cash.
