wordpress site need frontend and backend few tasks.

On the backend administration page an admin can add an invoice to the customer. It has status "pending" right now a customer can see all pending invoices I need to add in backend checkbox "make visible" so the customer can see the only invoice that has checked to be visible if a customer sees an invoice - next to it will be a button to pay for it There are some products that the customer can pay for, same button "Order" I need next to the invoice, which admin added to the customer. Attached screenshot for your idea of work. Budget 30$ and 2 days deadlines. Only experts apply. No time wasters. Thanks
