What type of commission can I expect as an independent for auto insurance?

I currently have my L&H, and am looking to add P&C license. I want to work as an independent & I understand that Progressive is a good company for that. Of course, if you know of any others, please feel free to let me know, so I can do good comparisons! My question is, what type of payout is the "norm" for indi auto? I know when you work for the companies, just like with L&H, the payout is considerably lower than when you are indi. Also, I dont think that the payout is nearly the same as L&H. Is that so? How do the renewals work? Thanks!
