Hello!
I work with PHP for last 5 years and have created hundreds of different skills, including a lot of web scrapers, including Amazon ( us and ca), Yahoo, Google, Facebook, Twitter, and Ebay.
Script will work next way: You will have input csv file, in which You will write listing information( but i need more information what exact listing You need, by product number( UPC,Asin) or listing of specific seller, or category?,
Then script will connect to ebay via api request, get data You need, and input it back to output csv.
As i have done similar project with Ebay, it will take about 7 hours of coding,to write your script.
If You need somebody who can manage really difficult thing, I am right person, I am not indian who use recorded or stolen scripts, all my scripts work with 100% accuracy and performance.
Hope for Your respond,
Regards,
Vlad.
