Hello,
Supposing that the 3 distributors' online catalogs are accessible so that to extract the data using code, the necessary data can be collected in approx. 3-4 days. Then we can use this new catalog to upload them on your ebay account. The info I need for now is the URLs for these 3 online catalogs.
A few words about me: I'm developing VBA and Perl programs for more than 15 years. Last 4 years I worked (and still I'm working) for online sellers, mainly US and UK, on all major marketplaces. I started creating scrapper programs, but finally I have dealt with almost everything, so that I have gain a great experience in using amazon, ebay and play APIs, as well as using many uploading, orders and inventory management tools and also repricers, like SellerCloud, LinnWorks, ChannelMax, eSeller, and many more.
Looking forward to hear from you,
Kind regards,
Chriskerpini
