Build a Website

Hello, we are searching someone to build a simple application which will be connected over API (Private apps) to Shopify and it will be able to be connected to more Shopify stores. Please check attached screenshots for how it should look (simple): Functions: 1. Choose a Shopify store from dropdown 2. See all orders from this shopify store in this app 3. Sort orders by (Financial status, Fulfillment status, Invoice status) 4. Be able to choose orders one by one or all at the same time 5. Be able to pop-up PICK LIST for selected orders 6. Be able to export orders as .csv file 7. Be able to import orders back to this app with another .csv file to add tracking numbers to orders and to change Fulfillment status to Fulfilled (this add tracking numbers over API connection to Shopify store and mark status as Fulfilled) 8. Be able to search by tracking number or order ID the orders directly from app and with use of simple barcode reader by scanning shipping label (it need read out tracking number) 9. Be able to connect with another API to make invoices in the invoicing application 10. If you cancel the order in application it must cancel it in Shopify as well and make storno of invoice over another API 11. Be able to connect a new Shopify webstore by inserting API credentials in application 12. Later we will want to add more functionalities.... The application look should be simple and usefull (like on screenshots). With API connection to Shopify the work should not be difficult for real experts. Timeline is 1-2 days maximum as we are in big hurry! Please bid only if you fully understand the scope of what we want and if you are ABLE TO START IMMEDIATELY. Please ask if you want login to check the existing app (its not anymore connected with Shopify store/s but you can see how it looks). Thanks!
