You can find a variety of companies online to help you with your market research. For example: Sundale Research's (sundaleresearch.com) primary goal is to provide new and mature businesses with objective, accurate industry data and market analysis on a wide range of topics. Their market research is intended to save you time and money while keeping up with industry trends. But your idea may be so new that you may also need to talk to potential customers, host some focus groups, talk to an ad agency, or maybe even make a prototype and float it past some people. Be prepared to spend the time. Remember, it's not about the Plan but the Planning.
Your marketing efforts do not have to be expensive. In many cases, companies that don't have marketing plans spend more than is necessary to reach their customers. With a plan that will spell out the ways you will market your company, you will save money and energy on your business marketing efforts. Creating an effective marketing plan is one of the most crucial elements of planning for your business.
