Please make the first statement in your response "I have built scrapers before" so that I know you read the proposal.
The best way to do this would be to set up some kind of scraper that will scrape all the ebay item ID's for a specific seller and add them to a CSV. Each item ID will be a different cell in the CSV. Some of the stores are very large and could have up to 500,000 products, so this process that is built needs to be able to handle a project of this scale. For example: Seller Q-E-Parts-1-888-219-7710 has roughly 261,000 items in his store. So I would need you to deliver a CSV with all 261,000 item ID's. I would like to repeat this process with multiple sellers, so I will pay you on delivery of the results from the first seller, then I will need you to set the software up on it's own server so that I can run it for another seller when ever I so choose. We can make the 2nd part a separate payment.
