Website re-build, e-commerce, client login, user login, invoicing

my website mobilephone dot icu needs to be rebuilt. You will start by creating a portal for users to create an account that includes saving their information and credit card information for current and future purchases. The user portal must invoice the client and charge card every time a technician is done fixing a phone. Also the user or client after logging in has to have the ability to let us know how many units (phones or other item) have for my technician to pick up and at what location.
