This is such a great resource that you are providing and you give it away for
free. I love seeing websites that understand the value of providing a quality
resource for free. It is the old what goes around comes around routine. Did

A good place for inspirations are local newspapers and magazines. Go to the classified ads section, and take note of the services that people are looking for and you could start from there. Take note of the services that you can provide, that are within your interest, use your imagination...and act on it.
