Data scrapper engine

Hello, We need a programmer with web scrapping knowledges, to develop a software to scrap data from online shops, online travel agencies, hotels... for price comparison purposes. As the system will be running in a Linux Server, it must be developed in a Linux friendly language (preferably PHP). The development have to be connected in a MySQL database which is already created, in order to store all the data obtained by the scraper. ** We only need the software for mining data for the websites required, with a socket connected into a MySQL database. No admin panels or user-ends are needed ** If you are interested, don't hesitate to contact us for more details.
