Amazon AWS project Excel Plugin

I need code written that will take an Excel spreadsheet that has a list of products and then when I push a button it will gather information via Amazon AWS and add that information as columns to the spreadsheet. The originating Excel sheet will include the following information: Brand Model Number UPC ProductName ItemCost Weight Button A, will be 'FIND ASIN' and it will return the corresponding Amazon ASIN (unique product identifier) for this item, and add that to a new column Button B, will be 'FIND LOWEST PRICE' will take the lowest selling price of the item on Amazon (including shipping) and place that in a new column Button C, will be 'Calculate Profit', it will subtract the ItemCost value from the lowest price, also considering a handling fee for shipping. we will then place in a column the profit margin, and another column to show the percentage of the profit margin compared the the cost.
