The Concept: After the job is complete you offer to help the homeowner host a party for their neighbors and friends to show off the work done on their home.
The 5 T's:
Topic: Throw a party to highlight the new addition to the home.
Tool: Cocktail napkins with your contact information on it and business cards next to the refreshments.
Taking Part: Attend the party and highlight some of your favorite features of the project.
Tracking: Use your own internal system to determine ROI.
