Birddogging in WA?

[John Salmi]

I'm new to BP and I want to get into REI by starting out as a birddog. I met with a RE agent who wanted to work with me but was told by his brokerage that it was illegal in the state of WA for "an unlicensed person to receive a fee contingent on closing". I was wondering if there is a legal way for me to do this or is it just that a "licensed" person cannot pay a fee that way. Any help?? Thanx much
