Crawl URL & parse data to .csv

This project is only for a programmer will be available via telephone or windows messenger. (I have tried to do this project several times via internet with outside U.S. programmers, communication of the details of the project was impossible). Basically, I need a php script to crawl and parse product description and pricing information from a supplier/distributor website, from multiple product information pages. The dealer pages (that is me) require a login which will be provided to the winning programmer. That parsed information will be saved to a .csv or tab delimited txt file on my own server and allow me to 'save and open' the parsed file via my browser (will open in MSExcel). I use the data to populate an oscommerce store product database. This is actually an easy project - I have several of these working scripts already, I simply need a new one that will crawl and parse faster and save the info in a different column format. The working scripts that I have were written by a U.S. php programmer who is no longer available. Looking forward to working with a programmer VERY experienced with php and crawling.
