One thing I always do is have a bunch of flyers or business cards,.. if no one is home, drop one through the door, and make a note of it. Call back a day or 2 later, while its fresh in their mind.
And also, things like a flyer or a bunch of cards on the supermarket notice boards, doctors & Dentists waiting rooms etc will bring in a few jobs. Not always in your preferred area,.. but any work is better than none.
Have you got sign writing on your vehicle yet? Also very effective advertising, pays for itself quicker than you'd imagine!
