Selling a business in Oregon

[Alison Anderson]

I am a licensed broker and own a real estate firm in Washington.  I am working with a buyer who has found a business right over the border in Oregon where I am not licensed as a broker.  He is looking at a business, not just the land.  In this case, is it legal for me to act in the capacity of a finder and charge a finder's fee considering he negotiates the deal himself?  Could I legally act in the capacity of a business consultant?  If so, how do I legally do this and what documentation to I provide to escrow in order to be compensated?
