scrape website for user ratings

I'm doing some research and I need a lot of user/member data from EBay. I need a list of (all?) members names and ratings for each other. So for each EBay member, I need to know all the members they rated and what the rating was (positive or negative). The data could be delivered in a database or delimited file. The data should be as comprehensive as possible. Also required, is the dates of each rating as well. Nice to have, but not required would be the dollar amount of the transaction for which the rating was given. I realize that this will be a significant website scraping endeavor - please tell me if you have experience or ideas for doing this. It's important that the data be as comprehensive and accurate as possible - the data provided will be tested with random sampling before payment is provided. I need lots of good data! ## Deliverables The data being gathered is publicly ratings and user aliases available via the EBay website. The coder must gather the data from the public website through legal means and provide it in a delimited text format or in a database. Required Data is as follows: For each transaction: Buyer Alias, Seller Alias, Date of Transaction, Rating Buyer gives to Seller, Rating Seller gives to Buyer, and (nice to have) the dollar amount of the transaction. The data will be tested for accuracy before being accepted. I will test the data with random samplings and will accept no mistakes (inaccurate data will cause my research to be useless!). It would be nice to have the scraping code or executable too, so I can repeat the process if needed. ## Platform data should be provided in delimited ascii text format or in a standard database format any platform should be ok.
