An app for android and IOS. I need an app to sell vegetables and products, take credit cards, and offer delivery dates and times for the customer to select. The customer downloads the app, inserts user name and address. The address sets the geographical location and sends notice to the neighborhood's company grower/seller (seller) selling in that area. We need to offer the app to each neighborhood seller and be able to upload their logo, personal data (email and number), and city block limits. Each neighborhood seller markets their app to their own customers and all reviews are limited to only that seller. If a seller fails, we need to remove their data, including reviews, and start over with a new seller using the core of the app. We need to start with a prototype and design as we go, and scale as neighborhoods grow. We are looking for a simple app first to test. We can eliminate the credit card payment part for now - so we need two proposals: one with credit card payments and one without. Important: each seller needs to upload the seller's logo, user name and phone number, pictures of the products and vegetables as seasons and harvests change.
