I can install a search engine on your website for much less than what some organizations pay each year for subscription-based software. 

The search software I use is maintenance-free and will crawl your website frequently so that search results include your latest content updates. 

Your search results page will contain no advertisements of any kind and will match the style of your website perfectly.  The software searches all kinds of web pages, as well as PDFs, and performs searches fast.
