Coding a simple scraping tool in PHP for a single website

The function will be used on my webserver and will be part of my overall web application. The function is to grab data of products of a large dutch retailer. User interface to input parameters. Start button. When button pressed program will load first page into memory and start storing the data in PhPMyadmin table. Each product as a new entry. On screen the data that is stored will be shown in a table for X seconds (parameter as set) and the page will refresh to start the new sequence, unless the last page is reached. If an execption is encountered the scraping will hold and show the exception on screen. For the data to be grabbed a few dynamic calculations (or exception rules) need to be made. All is specified. Details upon request. Experienced developers will do this within a few hours. Please let me know the cost. Kind regards, David
