BNI 198: Show Submission! - How to use BNI when too busy for more referrals

This week we answer a show submission!  The question is: I am a landscaper, I don't have the funds to build a new crew mid season to handle more referrals.  In order to provide the best service I can't take on more clients this year, even with hiring more people (which I have) I just can't take more business.  Great problem but besides passing referrals, one-to-ones, and meetings how can I still benefit this year from BNI?  I want to plan for next year already to handle 2-3 more crews.  What's your advice?
