The best place to for your advertising is on the mobile grooming vehicle itself. You should prominently feature your business logo and contact information on the sides and rear of the vehicle, whether through a custom paint job or utilizing large magnets affixed to the doors.
Additional advertising can be posted on the bulletin boards of vet clinics, animal shelters, pet stores, or other animal related businesses. You may also be able to develop a reciprocal referral arrangement with local animal service providers such as dog walkers, pet sitters, doggie day cares, and pet photographers.
You might also consider giving a special discount for first-time customers as well as customers who refer their friends to you. Creating a website or email newsletter can also create additional advertising exposure and keep your current clients up to date on your schedule and promotional offers.
