Searchable Part Feed

We have 3 different feeds in three different formats I need all three to be combined into one big feed and some other minor changes will need to be made. I would prefer the final feed to be in excel format so I can use it in our store's computers. We then would like to take this feed and put it online so our customers can search throught the feed by description/manufactuer part number/company part number. The cost should then be duplicated unless the cost is under 2.00 then we want the price to be tripled. And if the cost is under 1.00 then the price should be set to 2.49. I have attached the look and feel of the public interface. If the consumer searchs for filter in the description box then all products with the word filter in the description should be displayed. When the customer clicks on the part in the display box I want it to be added to their shopping cart with a shipping charge of 5.25. Our shopping cart is [login to view URL] so it should be simple to have this part done. The above is a basic summary of what we need done. - We do require all rights to this project and the retailing rights. - When bidding please be specific and detailed according to this project. Generic bids will not be accepted. --- DO NOT BID IF YOU CANNOT CREATE WHAT WE NEED --- ------ DO NOT BID IF WE HAVE PREVIOUSLY FIRED YOU ------ If you are good and can complete this project we will give you first chance on future projects.
