All above suggestions are great. I have really good success with door hangers in slow times. Just keep after it. You have to let everybody in your target market know you are there, who you are, and what you do, this doesn't happen over night. Go to businesses and introduce yourself find out if they currently have someone servicing their store. Take your rig with you and offer free demos while you are there. Cold call set up a free demo. Yellow page ads, newspaper ads, community directory ads, chamber of commerce. Have uniforms, brochures, cards, flyers, website, professionally designed. Put your logo on everything thats who you you are. The more people see that logo the more likely they will be to call you when ready for your services. Offer discounts for referrals that book a job with you. And most of all when you do get those jobs do them at the highest quality and more work will follow, be the best at what you do. Read here and other boards and you will learn more than you ever thought possible about the pressure washing industry. There is wealth of great knowledge here that people who have been in the industry for many many years are willing to share to better the industry. I'm Just ranting now but hope this helps get the gears turning.
