Advertise in Print and Local Electronic Media
In spite of the Internet, sales are still made by placing ads in newspapers and magazines, as well as running an advertising spot on radio stations. Assuming the products you offer would be of interest to local consumers, look into using these resources as well. The rates are often very inexpensive and have a lot of potential to attract customers.
As you continue to expand your client base, you will come upon other ways to grow your business that may be especially relevant to your products and your goals for the business. Always keep an open mind, since you never know when an opportunity to move your company along will present itself.
