Before you start advertising, decide what image you want to portray on your advertising material. For branding purposes (recognition), be consistent in all marketing materials that you plan to use. If you have a logo, use it on all your advertising materials. It is best to have a website developed before you start advertising. Stick with the same logo and colors on both your printed advertising, and on your website. The internet is now the main medium of communication and it's where many prospective clients will turn first to find you. Having a website shows clients that you're serious about your business and it allows them research your business in their own time. Being busy, it's the easiest place for clients to check out your credentials, promises, service offerings, etc.––indeed, many workers will use work time to find your site, likely the largest source of clients needing your services.  Many website deals are very affordable. If you use a web designer and hosting package, this will help to make your company appear more professional. The more information you can include, the better, including testimonials as you get them. In addition to your website, advertise on Craigslist, and if you can, Angie's List. Free advertising is as good as the paid! Start a Facebook business page and a Google+ one too. You can do all sorts of fun things to encourage clients to visit your site, participate in competitions and quizzes and leave testimonials if you put in a little effort. Advertising your company and your image is essential to getting your services known and recognized.  Advertise in a local paper with a text ad. Try to come up with an eye-catching ad. Do not sell your service based on low rates––sell your service based on your quality of work and what you can do for the client that other companies do not. There is a lot of competition in the cleaning service industry but by being the best and staying that way, you will stand out from the rest. Having your business name and contact information on your vehicle is a great way to advertise. It's recommended to use vinyl lettering. The lettering looks much more professional than the magnetic signs. Print flyers. You can print nice flyers on your home computer, invest in some professional flyers. Hang flyers at hair dressers, laundromats, restaurants, bakeries, grocery stores, etc. Put flyers on car windows at local groceries stores and businesses. You can even go door to door in your targeted neighborhoods. Make door hangers. When people get flyers or ads in their mailbox they usually throw them away with the junk mail. A door hanger may just be the ticket to getting them to look at your ad. Pick the neighborhood you would like to work in and hang the door hangers on the door knobs. Give your business cards to friends and family members, people you meet, on public boards, anywhere you can. You can also ask your local businesses if you can leave some cards on their counters, especially places where cleaning, or just "clean" are on people's minds: the dry cleaner's, day care centers (parents want clean homes for their kids!), supermarkets, and other places like that.  Make sure your contracts and invoices are ready. A great way to obtain new clients is through a referral program. Offer existing clients a discount when they refer a friend. You can give your existing clients a discount when the friend uses your services three times, for example.
