Datacrawlers for 10 websites

I would need crawlers to crawl 10 different sites (see attachment). It can be built with php, ruby or python. We would like to crawl the rental ads. The crawlers should be able to loop all rental ads and get url for all images and the main description text. It shouldn't use headless browsers to emulate a browser, that takes up too many ressources. Instead it could use curl to get the html and then parse it to get all the links and to on.
