Etsy API Integration & Google Sheets System

I need a professional API integration that pulls data from our Etsy stores into Google Sheets on a daily basis. The data includes sales, visitor counts, favorites, reviews, messages and listing information. In addition to this, I would like a system set up on Google Sheets to track employee performance and workflow.

Key Components:
- Daily updates from Etsy API to Google Sheets
- A structured performance and workflow tracking system on Google Sheets
- Optimizing the system for data security and functionality

If you have previous experience with similar tasks, I would appreciate you sharing your insights and how long you would estimate the project would take, along with your proposed budget.

I prefer communication in Turkish and would like to prioritize freelancers who speak Turkish.

Thank you, looking forward to your proposals!
