Ready to make the jump in North Atlanta

I'm a newbie from Canton, GA. I've spent the last few months reading countless blogs, listening to podcasts on every run and every ride to work. Yesterday, I turned in my resignation letter after ten years of breaking my back in Healthcare as an X-ray tech at my hospital. I'm ready to jump in and pursue this venture with my husband. I'm seeking to network and pick the brains of any investors in the Canton, Woodstock, Marietta, and other North Atlanta areas. 

My first question is regarding the structuring of my business. Should I speak to an accountant and establish an LLC or whatever, BEFORE I aquire my first property? Any recommendations on this and how to get started?
