SSH SFTP tunnel.

If you are successful, we can use you for further building of this app. We are unsure of the cost and time it will take to build this. Software needs to do as follows: -Create a reverse tunnel back to a host name we can hard code and the user cannot change. (it's okay to include plink to save time) -Must ask user the port of the reverse tunnel. -Must Auto reconnect upon failure. -Installer creates a windows service for both tunnel and SSH server, allowing us to SSH into that windows machine via DOS prompt type of command line, NOT bash/linux style. This would ask the user to input the username and password. -Must be able to access CUSTOM and ALL environmental variables within windows from the command line. Not just PATH and windows vars. (Must be able to echo %CUSTOMVAR% at the command line. -Request of SSH key would be required for input to connect the reverse tunnel also. -Our Icon sits in taskbar, with connection info. Current Connection Status, Time Connected no password information may be view-able by opening a configuration. Additionally, Not required yet, but will be unless we figure another solution if it doesn't fit budget -Able to SFTP through tunnel to a specified home directory A perfect combination would be myenctunnel and freesshd in one program with our branding.
