Very basic question: RE License, MLS and Agents

[Eric Stieler]

I'm new to Real Estate investing and have a very basic (i.e. dumb) question. 

My aim is to secure my license in Georgia and get access to the professional MLS so I can begin hunting and securing properties independently.  If I understand the licensing requirements correctly, I have to be tied to a Real Estate Broker to get my license. Endorsed by them or affiliated with them. 

I haven't made a connection with a local Agency yet.  I didn't know why the RE Broker would want to endorse me or work with me if all I'm doing is hunting for my own investment opportunities.  How do they get benefit from that relationship too?
