python web scraping script

Looking for someone to make a small web scraping script that scrapes an ebay store and then cross checks them on amazon to see if it's cheaper to buy on ebay. Can use selenium, requests, bs4 whatever makes it fastest. To check they are the same product I would recommend using the library fuzzywuzzy however if you have another way I am more then open. Could also implement a simple computer vision AI to cross check the images however this could seriously sacrifice speed so this is optional. Needs to be fast but not so fast as to get blocked so will need a proxy.
