Commerco start point portal sites are developed to serve a network of companies related to, in this case, Contracting. Commerco views start point portals as a metaphor for business districts. As in the real world, some districts, like malls, are focused more to consumers, while others, like financial districts, tend to be more a gather place for business. Because the Internet is not a physical place, there are many more resources than time to find, visit and remember them. These resources are also distributed all over the world, which makes developing start points for a given resource, a logical concept.
Search engines do a tremendous job of gathering all Internet resources.

To better focus this general term, vertical market portals under Contracting. Net will focus attention to a more specific or related area of interest.
