Investor-Friendly Brokerages?

[Juan Castro]

Hey everyone, 

I'm from Minneapolis, Minnesota and I was wondering if anyone from the area knows of an investor-friendly brokerage for Real Estate Agents? I'm just getting into Real Estate investing and want to make sure I'm not extremely limited with the things I can do from my brokerage while working as a private investor. Example: Having to use their forms only, giving them a cut of my profits, etc.

Hope someone can help, this would be a huge help for me.

Thanks!
