I can't find you a video but I do have some suggestions.
I shoot favorably left handed but, during a game, it's 50/50 left and right. Depending on the cover, I will switch from left to right. That's where the most practice is needed. The switch.
When going from left to right on the move, I lower my center of gravity to improve balance. It may kill the next day depending on when the last time I used those muscles, but it's a GOOD burn
It is sort of like writing with your opposite hand too, practice makes damn near perfect.
A vert grip is amazing for keeping the barrel steady and in line with your sight/scope.
Keep your elbows in, unless you want to lose them.
