I am brand new to insurance

I am a real estate broker and have my own independent office but would like to star also with insurance, I just got my P&C licenses and not afiliated with any insurance entity yet, what would be the best way to get started, and what commission or commission split I should expect, shuld I work with an independent broker first or with a insurance company? ca some one please give me some ligth on the starting up of this business?
I sincerely appreciate it.
