Build website/Online Store with Customer login

We need a reliable contractor to finish a half completed website/online store. Store/website is built entirely on code, and not using joomla, Drupal or any of those platforms. Alot of the coding has been based in Java React. The website is being hosted by Amazon Web Services. Services being used are: EC2 & RDS Code is stored at Bit Bucket. Contractor needs to know how to these two systems work. Here is the partly finished website: [login to view URL] This is inside the customer login area. Here a customer can view all their information including current order, order history, invoices, profile details ect. ect. If you click on Submit Order, you will see how the online form/store works. There are many elements and stages to this website that need to be completed. TASK REQUIREMENT (1st Stage) 1. Create an invoice page. Please see the uploaded file on what it should look like. 2. Link information from MY CURRENT ORDER into the invoice. So once a client submits an order, it will appear in the MY CURRENT ORDER panel. All relevant information from this order needs to automatically feed into the newly created invoice from Paypal. A customer should be able to view this invoice by clicking on the invoice button inside MY CURRENT ORDER panel. Information is fed from Paypal using API's (currently our only payment method). For this first stage of development, I will set an hourly rate. If the contractor can successfully meet the requirements, then I will be happy to discuss a fixed price for other elements of the website and set milestones accordingly. Please make sure you read the brief carefully and take the time to look at the current state of website so you understand the requirements before hand. I am looking for someone skilled enough to complete all components of this website moving forward in a timely manner.
