Hello there,
I see you have 264 variations for every product you are going to upload, I have worked with this amount of content before but on other e-commerce sites like Shopify, and Woocommerce on WordPress.
I assure you I will do my best to upload all of the products sent to me, I have a few questions to assure you a good service.
1- How am I going to receive the 60 products? Excel sheet with pictures? Are they uploaded online and I'm will download it?
2- I understand everybody wants the job done ASAP, but the process, If done manually will take time, is it okay for you?
