Standard Real Estate Contracts For Georgia?

[Terry France]

Hello, 

I'm getting started and I actually have 2 hot prospects I expect to be calling on shortly to see if we can agree on terms for a property.  I want to make sure I have the proper paperwork on hard before I call, so I need to make sure I have the right contracts so everything is fully legal and compliant here in Atlanta/Georgia.

One of them is a regular residential property, the other is an 5+ unit property, which I understand is classified as commercial. 

So how and where do I get a standard Georgia residential contract as well as a commercial property contract? I've been told the residential one is pretty standard and can be obtained (or purchased) through many different sources locally... but that the commercial one might need to be customized by an attorney. Is that correct?  Can someone point me to where I'd be able to pick up (or possibly download ) these contracts I'd need?

Thanks in advance for your help.
