Database Cleanup

This is a very straightforward but tedious project. I have a spreadsheet of several thousand Amazon items that I have a product# and name/description but no ASIN. About 95% of the records likely exist in Amazon, so you need to just enter the model# and then examine the results to find the correct matching item and then enter the ASIN in the spreadsheet. It should take an experience internet data entry person about 5-15 seconds per item to make a match. Looking for a steady stream of matched records per day until complete or until I have enough records, so quote how much you think you can do per day and the cost per day. I may not need the entire list done for this project. Accuracy is of the upmost! Thanks.
