124835 NEED WEB EXTRACTOR / WEB SCARP

Hello Coders,

I need a program which will perform two different tasks:

1) Extract product information from [url removed, login to view] stores

2) Check product prices on [url removed, login to view]

Both of these tasks are independent of each other. So do not mix or confuse them with each other. These tasks have nothing to do with each other. Each task will be performed individually. See the details below for each task:

1) Extract product information from [url removed, login to view] stores

I will enter the ebay store name, the program will go to that store, click on its listings one-by-one and extract the following information from each listing:

- item number

- item name

- upc number

- item price

- shipping price

The extracted information will be stored in either text or excel file whichever works faster for the program.

The program should be fast enough to process thousands of items.

I should be able to pause, stop or restart the program.

I will give more details of this task to the interested bidders.

2) Check product prices on [url removed, login to view]

The program will take each upc number from the column "upc" of the excel file (sample file attached), enter it in the "Search" field of ebay.com. If the upc is found, check its price under ebay stores listings and compare it with my price in column "sale-price" and then determine the rank based on the price comparison. For example, search for upc number 14381411928 and compare the prices of ebay stores with my price of 3.25. Based on the comparison, my rank would be 7 because there are 6 ebay stores with lower price than mine. Then put my rank in the next blank column of the excel file which is column F and it will be called "Rank". If the upc is not found on [url removed, login to view] then put "Not Found" in the column "Rank".

There will be thousands of upc's to search for. Therefore the program should be fast and efficient.

I should be able to pause, stop or restart the program.

Please show me a demo of the second feature "Check product prices on [url removed, login to view]" and I will select your bid right away.

Thank you.
