Scraper plugin for my Shopify store

I need scraper from [login to view URL] for my Shopify store. I see this tool in this way: 1. To every category that I created on my Shopify store I connect the link from which bot will scrap products with all information that they have and all subcategories also. (possibility to change this link to another from the same store is needed). 2. Scraper also must work with links like this: [login to view URL] 3. I planning to have about 50k products, so scraper must work 24/7 to scrap new products and update price and stock availability. (If they didn’t find a products they had to delete them) 4. It must have anti-robot captcha protection proxy’s .... 5. If shipping not free they. 6. If you have any advice please let me know.
