Hello we are interested to have a part developed inside our website with functionality similar to dropbox. We need the users of our site to be able to upload and share their files, to use media player to stream their media files, document viewer and if possible editor and photo slideshow viewer. We need to be able to create account levels from the backend and paypal integration for them to pay for premium. It's a rather simple project as the site is ready and you just have to code this part so we need it fast. If you can also create the windows/mac client then please name that price too and we will soon get our decision.
