Swing analysis, one week for one fix

So I've been working on tempo and take away angle. But now I've noticed my most glaring problem is my head and hip sway, especially on driver where my body is chasing after the ball to the target. I see in a lot of analysis, you really want the body behind the ball on driver.

I've got one week to go until I set my benchmark round, anyone have any drills or perhaps think they something else is a bigger problem?

Update: Thanks to a few r/golfers comments my first day with fixes is looking better already! https://www.youtube.com/watch?v=-xNEfSKS3UA
