data extraction, scraping from host sites & display on our site

I'm looking to hire a coder on a long term basis. my projects almost always involve data extraction/ scraping from host sites and then displaying that data on our website. At this time, the main project will involve getting listings from a car trader website such as ( **[login to view URL]** ) and then displaying all these listings on our websites car sales section which is ( **[login to view URL]** ) The coder will be responsible to make sure the data is kept up to date on our website so this can be done by setting crons to run scripts which scrape the host site on a regular basis and then update our website databse with the latest listings for this trader. Old listings which have been removed by the host site must also be removed from our site. I have been working with data extraction coders for many years now and our website has a few similar sections where the same principle is working nicely. I am looking for a coder who can give me a good price per site ( data extraction ) and in return I can promise roughly 50 project sites where the same data extraction + display on our site will take place. In addition to this site, I also have many other websites ( non automotive related ) but the same data extraction + display principle will apply so much more work is guaranteed to the right candidate. Please get in touch with me ONLY if you feel confident that you can do this job quickly and efficiently and please quote me a price per site scrape with your replies. I will also need to see examples of previous work you may have carried out on a similar theme.
