QR reader app that opens a specific URL website that would give people access to database information.

I am looking to have an application written that would allow anyone to us a standard QR reader on a mobile device to open a URL or (website) Making this data easy to get to. The Website/ database would consist with simple clean buttons interface that would then take you to Pdf, Word, docs, excel documents view-able on a mobile device or computer. Any generic QR reader could launch to the site as well. Back side of the website / database would be a pretty simple database that would allow a user to drag and drop multiple files/ associate them with a url link. EXAMPLE OF HOW THE DATABASE WOULD WORK: 1. Open Database Interface 2. Put in unique customer name : Verizon 3. Answer City name: San Diego 4. Answer Bldg name: Bldg X 5. Answer Bldg Floor: 1 6. Answer Room Number: 1001 Would create a URL similar to : [login to view URL] In that URL page you could create a button, name the buttons and drop documents into the database so when you arrive at the URL above you could select a button with the documents you are looking for. Directory tree would be created so information could not be duplicated. I would also want to be able to print a pre formatted sticker size with QR code using the above URL and company logo on a sticker to apply on the site. This application would allow users to use smart devices to quickly find documents. I am not sure what to write this database in? looking for suggestions. Just looking for stability Programmer would need to sign a confidentiality agreement.. Will send drawings and more detailed information upon award.
