I don't really care what language you will be using to write this program
First of all you should be familiar with amazon and Ecrater selling account listing process. I need a program that can list items on amazon, ecrater. plus this program should be able to store pictures and descriptions from different wholesale sites, that I would like to have business with. And then use these pictures and descriptions to create listings on Amazon and Ecrater. For example I like some wholesaler with website [url removed, login to view], so I turn on my program set it for that specific site and it copies all descriptions and pictures, then I open amazon selling account and this program creates listings with information that it obtained from that wholesaler.
