I am an ableton instructor and can teach to Ableton 101 spec or bespoke sessions.
1 full day in the studio (maybe 2 if you wanna go into advanced stuff) would be enough to get you fully up to speed for live pa AND production basics in ableton.

I`ve been regularly performing live all over the shop as Dirty Bass (previously) and Voidloss (currently) utilising ableton since 2003.
