Bulk FBA Fee Calculator in Google Sheets using Amazon API

I need a Google Sheet create where I am able to input a long list of Amazon ASIN's with the buy cost and it will calculate various ROI percentage sell prices. I would like it to calculate 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% ROI. This calculation needs to take into consideration and output in their own columns 1) Referral Fee for the appropriate category 2) Variable Closing Fee (If Applicable) 3) Order Handling Fee 4) Pick and Pack Fee 5) Weight Handling Fee I would also like the Excel Spreadsheet to output the items weight, height/width/depth dimensions, and items Category. The Amazon FBA fees should reflect the new fees that start on February 18, 2016. It needs to be easy for me to change the fees, for when Amazon changes the fee structure in the future. I DO NOT want this to work off of web scraping. It should run off the Amazon API and be accurate. The finished project should not be compiled. All source code, files, and file access needs to be made available so that another programmer may be able to work on it in the future. This project needs to include instructions on how to setup and run correctly. The project needs to have the options to make minor changes if needed during work. Fee calculation results show match the data found via Amazon @ [login to view URL]
