What about using your current client base to either set up meetings or tell them about your new wrapping program? One of the best ways of advertising is getting those first couple wraps under your belt and letting your customers advertise for you. Wrapping a company vehicle is a great advertising point too...then people can see your quality design and wrapping skills. I do not have experience cold calling but this strategy has been very effective for us. Have you wrapped a vehicle before or just starting to get into it? If you haven't had a lot of experience maybe wrap your vehicle a couple times and get some practice...then when you put that first one out it will be really good and the business will take off from there. Good Luck!
All very good advice. Pretty similar to some I offered right off the bat.
"Is your work vehicle wrapped in a high quality way with an effective, high quality design? If not, get on it ASAP. Nothing sells good work, like already existing good work.
How about your contractor friends who have businesses in the area? Offer to wrap a couple of their trucks for a greatly reduced price and chalk it up to advertising.
Several times a year, we choose a potential or existing client who is really easy to work with and open to our design ideas and we give them a knockout looking sign far above what they expected or were paying for. The word of mouth from them alone is worth its weight in gold."
