Search Engine For Space Related Web Sites (Score 1)

I'm contemplating a project to build a searchable database on the web of all web sites relevant to the commercialization of outer space. Before I begin such an enormous project, I need to know if anyone else has already initiated a project and have a working example available. My database will have a preference for publicly traded and privately held companies engaging in space burial, space tourism, launchers, and satellites. Anybody interested in helping me out with this project should drop me an email.
