You gotta have vehicle signs. Otherwise you will look too much like the creepy people on TV shows who drive white vans with no signs, and are always up to no good. When you are inside doing a job, stick some of your cards, fliers, etc., under your windshield wiper, or in some kind of card holder, so people can take one while walking by.
I have perforated window vinyl all around my van with my logo and number, I was talking about little signs that draw attention to the van, I have gotten jobs before off the van how it is designed now, I was pointing out for other people who may find it helpful to book extra jobs that I get more calls with magnets that have a call to action than with just my standard signs with my logo and number.
