I need a programmer to build a website with an internal search engine. Don't have a lot of money but I need help I'm a plumber.
If you need plumbing maybe some in trade. New Internet Business. THANKS >Removed< Search Engine is only for new site.

Several open source content management systems like Drupal and Joomla have search within the site and are free to use. There is a lot of info and tutorials available you may consider doing it yourself.
