you have to show them some value for using your program, or have a catchy web banner that you can pay someone to show for you.
Even giving the service away for free doesn't always help if hardly anyone knows that your web site exists nor does your product exist. Who outside of IWETHEY really knows about it anyway? How have you promoted it? Are you reaching your target clients somehow? It doesn't sell itself, it takes someone to sell it for you. If you cannot sell it, even for free, then you aren't going to have any customers using it.
