In many cases it is more convenient, cheaper and easy to work on your systems remotely. There are several ways that can be done and I am flexible. Some wants to be in control of when I am logging in to their systems, and others think it is a hassle to allow me in every time. In any case there is a tool for all scenarios.
You need to have an internet connection though. Normal hourly pricing applies for the time I am working, but you don’t have to pay for travel time etc.
