Google Sheets/Google Drive Migration to Microsoft Outlook 365/OneDrive

We have 3 Google Sheets that need to be migrated over to Outlook 365. Also, the Google Sheets use a Google Drive which contains scripts. Those scripts along with formulas, buttons and other functions need to be migrated over to the Office 365 platform and OneDrive. All functionality of the existing Google Sheets will need to be maintained in the Office 365 platform.
Please provide a ballpark estimate for consideration.
After the NDA agreement is signed, the files can be sent along with a request for a final fee.
