How much space and cost would it take for Ar15.com to have it's own internet search engine?

I was thinking to have our own search engine and maybe have it geared up to specifically find pro-gun and firearm based web sites that other sites may not list because they may be anti-gun or whatever. Adult-content too. [;D]
But then, if there is a decent search engine that would tie into AR15.com nicely, would that work better?
My question on having a search engine is to have AR15.com kind of like a homepage where we can not only have decent discussion forums, but also can search the internet within the same site.
