Customization of a PHP metasearch script

I need customization of a PHP metasearch script called K-Search, provided by [login to view URL] ([login to view URL]) so that it can meta-search for auto-classifieds. You can see the demo on [login to view URL] I’ll provide the winner with the full script for testing. You should provide following information about the project: price, time to complete, estimated cost to add new sites to be searched, cost per hour for additional jobs. The fundamental functionality of the script should stay unchanged. There are three things to be developed (as far as I see it): 1. modified engine files for every site to be searched for quering the site and parsing the results (I attach a sample engine file) 2. new page template with a search form (details below) 3. new page template with the results (details below) After succesfully completing this part, there a big chance for further developent.
