Programming "Search Field" on simple site ... php project

This is rather URGENT ... I need this done in the next 2-4 hours so I'm ready to select someone quickly. I posted this same project 7 hours ago, but the person I selected does not respond to communications and the old project post is being canceled. Please be confident you can handle setting up a custom search on a website. Search functionality needs to be setup ... I have a client's website that is already done, has the search field already installed on all the pages, but the search functionality and the programming of the search feature needs to be done. Please see the attached screen shot, [login to view URL], to view the domain name of the project. There are 2 other screen shots that may help you out. I have all FTP / Web Hosting Backoffice, etc. login details. Sphider (Google it) is an open source option ... or any other custom search you have experience with. Not looking to spend a lot for something so simple, but need to get this done fairly quickly. I look forward to working with you :). Feel free to send examples in PMB.
