Many new companies will put together a direct mailing list or use other mediums such as radio, TV and Internet advertising options. Also make sure that anything you send out represents you in a professional way. If designing marketing pieces is not something you are comfortable with, hire someone to do it for you. Spend the time and money to have a complete marketing package done. You should already have a business plan with a marketing section.
Some people further develop that section of the business plan to a stand-alone marketing plan.
How to get your business service or product known to its buying public is critical and worth spending time on, especially before you spend any money on marketing ads. Many people will approach you to purchase ads and while the prices might seem reasonable, any money spent would be wasted if the medium in which the ad is placed doesn't fit in with the objectives of your marketing plan. Know the difference between marketing and selling. While the ultimate goal of marketing may be to sell something, marketing is about getting your name out there in front of the people who will use your product or service. Try to stay focused on your audience, what you want them to learn about you, and the media that will reach them.
