App to Map Network Drive over SSH

Hi, We are looking for a developer to provide a Microsoft Windows- based client application that we can install on a PC. Installation should run like any standard application and work on Windows XP onwards. The application would need to ‘map a network drive’ to a defined location, for example “\\[login to view URL]\MyShare” across the internet. Therefore the application would need to run over SSH. An SSH key should be configured by the user during installation, or be added after the installation has completed. In addition each user should enter a username & password to authenticate to the remote mapped drive. The user should also be able to edit their username & password and change / update the SSH key when required. Once the drive has been mapped and the user successfully connected, they should be able to edit all files in that location (browse, open, rename, save, edit, copy, etc.) as if they were on the local device, for example via Windows Explorer / My Computer. The application should support multiple drive mappings, say up to five. Essentially this application should allow users to work on files directly from a Cloud Server, as if they were on a local computer or network server. Consideration should therefore be given to the possibilities of file compression when opening / closing files, possibly working at bit-level. We already have the servers (all tried and tested) we just need the application(s). Once phase one above is completed we would look at an App for Mobile devices and a MAC solution. Many thanks.
