Non-Indexible Database Driven Membership Website Using QR Codes

Model = Customer Visitor = User I'm an adult-context photographer (i.e. boudoir) of models. I have hundreds of models that utilize my services. I'd like a website that is membership built, meaning that every model can purchase his/her own page that only they can view (without being invited) by logging in. That means that no search engine, no crawlers, no query function, etc. will be able to find their page within the site. The only way that you will be able to view their page is with a QR code that is physically handed to you or emailed to you. The QR codes represent the non-guessable URL of that specific model. The physical QR code is printed however a digital QR code can be generated for the same models page which needs to expire 48 hours after creation for email purposes. The vistor can see no other model's page or anything else for that matter other than the page they were invited to view with the QR code. The website is nearly invisible from the internet (i.e. hidden) other than the home page. What technology is used to develop the site is not my field of specialty. However, the design needs to be a little darker and mysterious in nature. I have logos and any artwork you'd need in any format you'd prefer. Each model's page needs to be template customizable much like a dating website would be with photos, videos, bios, etc. On the home page needs to be a link to another public page for new models to sign-up and purchase their own page. There will need to be an eMerchant integration of some sorts for the Models to purchase supplies through the site such as marketing materials, prints, etc.
