Startup Idea: Centralized Networking Connections Manager for Contractors

Startup idea to develop a software program designed specifically for contractors to efficiently manage their networking connections. The program would store all information about contacts, including changes in contact methods, last contact time, occupation field, etc. This information could then be easily displayed and searched in a CMS, helping them to keep track of their network and potentially find more job opportunities.

I am a contractor who works with web related work(project management, wordpress site building, webmaster work, SEO optimazation, etc.)

I have difficulty keeping up with networking connections.

Even though there is a bunch of different resources(linkedIn, facebook, etc.) It would be nice to have a program that could keep all information about your contacts in your network. For example, changes in ways to contact them, the last time you contacted them, occupational field, etc. and dump these into a CMS that could display this information easily and allow one to query like a database to find relevant information.

This would help me keep better track of my connections and possibly lead me to more jobs.
