Rhododendrons: What to do with extra Rhododendrons?

I just purchased a home in Vancouver with four large Rhododendrons that have taken over part of the garden. I would like to remove them from my garden, but would hate to destroy them. I was thinking some local nurseries may purchase them, or possibly individuals. Is there a website or forum where someone can sell their fully grown plants? Can anyone recommend any options for me?

 

Craig's List, or the Buy and Sell, or the classified section of your community paper. Or of the major daily papers, come to think of it.
