AGRO ECOMMERCE STORE

I am interested in an Ecommerce store, which includes a website and App available for iOS AND ANDROID, something very similar to Amazon, to provide products from the field to producers and farmers in the field, I would like you to send me proposals from online stores and mainly that the website does not have problems with service drops, I would like something to assure me that part. I am attaching some images of examples that I have found, I am looking for something similar or better
