Trying to sell expertise in this field is hard, even when you have a lot of knowledge and contacts. The biggest issue is that people don't want to give remote logins to systems, to people far away.

I setup a trivial page at http://remote-sysadmin.com/ but getting attention has been very hard, even though I got a few contacts along the lines of "Please automate Debian updates", or "Please install plugin Foo for wordpress, plz".
