Hello,
I'm working with ebay, amazon, play and other marketplaces for more than 3 years, supporting online sellers mainly in the UK and USA. I have a good knowledge of the requirements and policies applied from each marketplace, also a very good level in using and managing many different uploading and managing tools and finally, I'm writing my own scripts using the available APIs in perl, php and VBA (Excel) if needed. Of course I can upload without any issues your products in max 2 days. I will need the products details (there is not attachment, by the way), the images links, and also your account's details for the uploading. I suppose that the images have the minimum resolution (500 pixels at least for the one dimension), so that to be accepted without conversions (which would be time-consuming, changing my estimation for the project's duration).
Looking forward to hear from you,
Kind regards,
chriskerpini
