Bot /Script /Spider program needed

We are looking for a repricing program which would entail the following. We are presently a merchant on [login to view URL] and would like a Bot /Script/Spider program which could scan the site and provide real time information regarding pricing on SKus we carry. The program would contain our list of Skus (approx 100) with our present price, Qty etc.. This info can be updated via a manual download and import via a .csv file. Upon demand, the program would scan [login to view URL]'s site and return information as follows. The name of the company, price, shipping and total price of for the company who has the buy box on the website. (Its the seller in center of product page with the big "add to Cart" button. When scan is complete, the program would provide this information next to our current price so we could determine if changes need to be made to our price and/or Qty available. We would like a one click option which would make our prices 1 cent lower (or other value we select) on all the skus we select. We then need the program, upon demand, to convert this information into a specific .csv formatted file (pursuant to [login to view URL]'s specified format) so that we can upload to [login to view URL] to effectuate the price change. We are looking for someone who can do this quickly.
