What to do when you don't get customers no matter how many times you put an advertisement, new or old?

There are several options facing businesses who are challenged with the need to develop new customer bases.  One action that businesses undertake is the hiring of a consultant or consulting agency.  These individuals examine the business and develop different approaches to generating revenue or attracting more clients.  A fee is charged for such services, but the advantage in receiving assistance from outside the company allows a "fresh set of eyes" to examine ways to generate client interest and develop new streams of revenue.  Another approach would be to develop a website or webpage that is linked to internet traffic within the organization.  This is not merely advertising, but an attempt to create "buzz" or interest within the industry, but creates a forum where the business is in the midst of activity, and can develop new paths to client interest.  Building off of this could be flexible pricing schemes and incentives offered that are designed to lure first time customers, in particular.   Finally, an approach to attracting more clients may lie in rexamination of company goals and its targeted audience.  Perhaps one reason why a strong client base is not being developed is because the audience and business services are not aligned properly.  Reevaluation might develop a stronger sense of connection between business servies and client needs.
