Dear Sir, I have been in Amazon business since long enough and running my own business Amazon marketplace. All I am doing through web services (APIs provided by Amazon marketplace for developers). I have outstanding knowledge of amazon infrastructure. I know how to upload amazon inventory, update quantity and prices. I also have knowledge as how to maintain the variants this marketplace.
Our aim is not to outbid but to satisfy our clients with outstanding work with good ROI.
Ready to go for you project. Thanks
