Yellowpages.com data extractor (web scraper)

Hi, I'm in need of a [login to view URL] data extractor. Just recently there was a project similar to this posted ([login to view URL] data extractor). I require an application that does the same - extracts [login to view URL] data and saves it to a CSV file. Fields required are as follows - Company Name - Category - Address line 1 - Address line 2 - State - Postcode - Tel - Fax - Website (if applicable) - Email (if applicable) - Date last updated from crawler. - must be able to extract the data from the sponsored listings. - Must be able to automatically or otherwise be able to extract the data from the continuing pages i.e. 2, 3, 4 onwards to get the full data. - save it all in a .CSV - We want the Source code and copyrights - The software should be in .Net and should be developed in c# - We want desktop software If you already get other scripts that can extract contacts from other web sites, please let me know. Also if you do a good job I will need you to add additional scripts for other yellow pages. Thanks
