Perhaps you would like to be a bit more explicit about your desires. There are a few quite different types of search engines. Some are for internal use within different sites, other are simply filters, or web-wide searchers like google or yahoo. Then there is a matter of all the functions it needs to perform according to your interests. I think the best way to solve that would be by filling a briefing with all the parameters that you are interested in so we can make you an offer.
Please request the briefing form via email ( darian @ ice-media.ro) if you are interested!
Greatness comes with hard work!
