Hi there!
While not a system administrator, I am a seasoned Ubuntu user; been using it since Ubuntu 12.04 came out. On a few occasions have had the need to upgrade my system too, and every time have been successful...
This upgrade and installation/setup of additional software should take between one and three hours, hence my fee.
Help me help you! I'm located in Vietnam, and although we're 7 hours ahead here, it's a non issue for me. I can get the job done at your earliest convenience.
Cheers, mate!
