I've had this bookmarked for years because every time I need to do it I need to refresh the exact steps... https://www.howtoforge.com/reverse-ssh-tunneling However, you're still going to need a common account on both machines and SSH forwarding through the router at his end which means you're going to have to send them instructions to follow either way before you can get in. Cut out the in between step and just get them to install TeamViewer or whatever instead - it's less likely to go wrong and once you're in you can setup a 'proper' remote access protocol to your liking instead.
