I have tried all kinds of ways from flyer rolled up and putin the door to knocking on doors to the news paper. But the 2 ways i found to be the most effective were 1. going to a printshop and getting doorhangers made. then getting my nephews to put them out in target neiborhoods on BIKE. this makes it 5 times faster.
2. I have frisbees made with our name and logo then drive through the neiborhood and toss away. (drawback to this is not to do it on a weekend cause the neiborhood kids will take every one!)
I hope this helps someone!
