Data fetcher tool

This project is to create a Data Fetching Tool which fetches data from specific Directory Sites such as Amazon , eBay, yellow pages and the output of the data should ideally be in Excel or csv format. These excel exported data would come out with categorization --> Company/Business name Nature of business Contact Person Contact E-mail Contact no. Website Yes/No. If yes, Website link to be given Basically, The tool should have capability to fetch in data from any directory link in given format as above. The tool should be able to fetch data according the parameters specified. Examples of tasks: - Fetch all companies under category: Electronics - Fetch all companies with / without websites - The tool could validate data and remove in duplicates. More info can be shared via PMB. Fair easy for someone who has already created such kind of data retrieval tool. Also, to note, This would be web tool specified under a link and uploaded on my web server after being duly verified and tested. Guys with demo of such kind of tool would be given preference so do give in link to such demos in pmb. Cheers
