Build a Website with File Uploading

Hi! I'm starting a local printing business. The idea is to sell bibliography and print copies of many documents. The user register on the website with email or facebook account. The user should upload .pdf, .doc, or .xls files, and each file generate one "print order" that I would print effectively later on my business printer machine. Each document uploaded should have attributes to modify, to describe the order. (The admin could add or delete attributes like "black color only" "color printing" "premium paper", etc) The user can see their uploaded document, production, and shipment status. The user could see online and download the documents uploaded. The user can change their info, put profile picture, change name, last name and password. The user should have order panel. One order per file uploaded From Admin site, I should see the documents, download them and change order status. It must be compatible with Mercadolibre and Mercadopago API's I know this its not the best project description but its a start.
