if youre a small shop, advertising isnt really what to do.. marketing and networking is. more one on one. financially there are reasons for this. If you want those PM me and I'll explain and we can work thru it.
as for ads, avoid any trade you're in competition with for the clients ad dollars. Signs should drive the prospects to the website, and the website should drive the prospect into the sales channel. the sales channel could be an online store for simple stuff, or a contact form for custom work.
Offsite signage has far better exposure than any other ad forum. find a place to put up a billboard to pint folks to your door. You'll get 50% of your clients from your signs, and so will your clients. 85% of your clients will come from a 5 mile radius of your shop in a typical retail operation. (on that - create a local impulse item that you can market with door to door coupon drop offs, maybe a banner for $2/psf. You want them to try you out.)
Google adwords does drive sales if you geographically focus it and dont try to be-all do-all sell-all. You do need to have a good web site that shows what the client wants to see.. remember - THINK LIKE THE CLIENT, NOT THE SIGN PROFESSIONAL. what do they want to buy? how do they want to buy it?
WRAP your truck/car/dog. Keep it simple and very legible. show off your skills, but have friends offer insight. if it cant be read at 250 feet, or in under 3 seconds, re-do it. keep copy to a minimum. we use just website and bold colors. If you cant get business from your own vehicles, you wont convince anyone to buy that product/service from you. spend good money on media to make your vehicle look nice.
WRAP yourself - create a shop uniform, be bold and wear it everywhere. Youre in the identity business after all . One shop i know used tiedyed shirts and a tiedyed car wrap to get great marketshare. An embroidered polo with nice pants can make a good everyday look. Also have something thats for higher end meetings. I knew one fashion district shop that dye sub'd fabric to be used in lined suits made for sales staff. For high end meetings we embroidered our logotype in a discrete matching color thread on striped long sleeve dress shirts, $85 a pop. I had logo cufflinks for me ($125) and logo earrings ($400) made for my female CFO. Our sales reps had embroidered ties. Yeah it sounds absurd, but it got compliments in almost every meeting we attended. And that brought business.
tip = Do not wear a polo or tshirt to a meeting with a person who is likely to wear a suit if youre bidding a major job for them.. perception of your status is still very important in business, and you'll feel and seem out of place. The dividing line seems to be about $10,000 in sales.
Then chamber of commerce.. go to the mixers, meetings and shmooze the people. Always wear your best uniform or suit. I use a lot of give aways there. We made alphabet keychains engraved with our name and phone number out of .080 aluminum as giveaways one year, people later came in and bought them they were so popular. We pad printed led keychain flashlights and gave them out with a blister pack that had our business card printed on reflective vinyl. also popular. pens, notepads, etc all work as giveaways, but people are picky about the swag they get. If you dont like doing it, having a give away is a great ice breaker. If still uncomfortable - have your wife/kids/employees/dog do it.
The members of those groups will connect you to others. Other local groups are also good, get involved and support pta, athletics, merchants assoc, Rotary, any place that gets you involved with the demographic that will buy from you.. Occasionally give a banner to their cause.. offer free banners as door prizes for their bigger meetings (i do 2x4 and 3x4), that gets you a free contact with a client face to face and theyre likely to do business with you. Ive even had a signco win the door prize, and he bought about $3500 a year from me after that.
The facts are simple, networking is what builds customers on a small budget. Looking great in your fleet and your crew reinforces your professionalism and skills in this industry.
