My question involves business law in the state of: Oregon

I will be getting my Oregon real estate license in a few weeks, and I was wondering if, in the state of Oregon, it would be wise to form a one person LLC IN ADDITION TO having Error/Ommissions insurance? My main purposes are to keep business and personal transactions (i.e. separate banking accounts) separate, and to protect any personal assets in the (hopefully) unlikely event that I am ever sued by someone for an amount beyond what the E/O insurance covers.

Thank you for your time!
