Scraper Bot Needed

I need a bespoke bot building that will record and analyse the past sales of a sellers items on ebay. It must also record the dates of when the past purchases were made. The aim of the bot is find all the items with the highest past sales in the shortest of amount of time. For example if you look at this item below: [login to view URL] You can see that it has 5 sold. If you click 5 sold it will show you what dates the purchases were made. I need a custom date range feature building in to the bot so if I wanted to see which items the user has sold the most of in the last week or two i would be able to do that. I would like the bot to display all the data in a table so that i can see which items have sold the most in the shortest amount of time depending on the date range i set. This current seller has over 1 million products on ebay. There shop is below: [login to view URL] I am looking to with with a partner on this project in exchange for them building the bot. I will show the coder once the bot is complete how to make money with it so they can use it on there own.
