Data Verification - Matching products

We have a system that takes products from one database and looks them up on eBay and Amazon. While the tool can match using keywords it isn't reliable enough to be able to match these automatically. The job is to log into our system and verify the products match. This is as simple as deselecting any product that isn't applicable (from 2 results) and clicking to accept. There are a few more critera to consider when matching the products but is it very simple. If the products don't match then you can just click skip - no other work required. We had someone locally spend an hour doing this and they managed to verify 500 at a stead pace. See the image for the interface and basic instructions. Please price per 2000 (approx 4 hours work) At the moment we have 2500 to verify, however we will be looking for short term work of 50,000 and long term of 250,000 plus
