Giving up on setting QLC+ by myself

[MyGreenhorn]

Hi,
would anybody mind helping me setting up QLC+ on a RPi3 against payment, so it will:
-start a show at e.g. 6 p.m.
-stop the show at e.g. 8 a.m.
-do this also after reboot
-allow me to access the RPi3 without monitor e.g. by RDP

I have managed to get the 8 necessary LED bars up and running.
Sometimes I can RDP via vnc-any into the system.
But as a Linux newbie I am not coping with the necessary steps
to make it a stable and rebootable system. I am still at 4.11
as I am totally afraid of updating the whole thing again.

Best regards
Klaus
