Document Uploading Program

I need a program made that allows the users of my website to upload documents in common formats such as pdf, word, or text., so their documents can be nicely displayed on my website. An example of what I am talking about is [login to view URL]'s iPaper software they developed for viewing documents. The program [login to view URL] has developed for document uploading and viewing is what I am looking to mimic. ONLY BID ON THIS PROJECT IF YOU ARE 100% CONFIDENT IN YOUR ABILITY TO MEET MY CRITERIA.
