eBay Repricer

I need a bot for my eBay business. The bot needs to get prices/quantity in stock from a website, and then automatically reflects these changes on my eBay listings. Also the program should facilitate listing said items from the website to eBay. Ideally, I would need someone that is familiar with converting amazon logistics tracking numbers to tracking numbers that are recognized by eBay. An example of a program like this is yaballe.com / priceyak.com Message me for more details.
