Edit shipping rates and logic in Magento 1

Hi everyone, I am looking for a freelancer who is able to help to edit the shipping rates and calculation logic in my Magento 1 shop. Would be great if you can export a table with values in excel/csv file for every storeview / country / product category, so that I can easily edit the rates and calculation logic. After that, we will import the updated file. My budget for this task is €20. Looking forward to hearing from you. Kind regards, Robert
