Cars Search Aggregator Website

I am looking for a skilled individual who has substantial knowledge in PHP, HTML and Javascript to design and develop a website for me. This website will require a user to be able to manipulate particular search results from various websites, and incorporate them into one website. I have not yet decided whether a database will be required, although database skills are also highly desirable. The entire solution will be discussed in complete detail with the successful bidder. The Website will have a mainpage, search page, and result page. I am looking to link approximately 7 websites in total. The successful candidate will be required to understand methods of Data scraping, or a similar method to retrieve information from websites given without providing feeds. If the project is successful, the individual will be contracted to work on a number of other future projects, based on the outcome of the initial project. I expect the project to be complete within one month. Before any other payments are provided, the successful bidder must provide a working example of the websites functionality, to prove that they are capable to complete the project. Any unsuccessful completion will lead to immediate termination. Exact details will be provided, with screen dumps and a thorough proposal to the successful candidate.
