Paralegals in Georgia | Realistic salary range and how to move up?

I have 2 years of law office experience (legal assistant/paralegal type duties) and a bachelor’s in Legal Studies.

For those in Georgia (especially Atlanta area):

•	What’s realistic pay for 2–3 years experience?

•	Does certification actually increase pay?

•	Is corporate/in-house better than small firms?

•	What skills increase salary fastest?

Trying to move from service work back into legal full time.
