I've sold my corporate clients on 8K, but from an acquisition perspective. For quick, 1-camera executive interviews, I can crop between 8K and 4K in post to make it look like a 2-camera shoot and they absolutely love it. 8K is all about acquisition... at least in my personal case.
I provide an estimate per project and split the total cost in three parts for the client; pre-production, production, and post production to ease total sticker shock. If they want further breakdown, i provide it for them. I charge a fair bit and have no problem walking away if they don't like my estimate. I'm lucky to have reached a point in my career where I can afford to let jobs go. Wasn't always that way though. It's a tough game for sure.
He's all sorts of awesome.
For corporate stuff, I've simplified big time over the last 5 years and I now get away with mostly using a minimalist kit that consists of two 1x1 LED lights, an overhead drumlight, two 5-1 reflectors, one of those small 4"x6" AA battery powered LEDs when I can't get an eye light from my 1x1s, and a 650w tungsten (not used often but when it is, it's usually for background lighting). If I need punch, I'll rent a k5600 joker bug 800. I started breaking down all my setups on IG if anyone wants to see how I get away with it. Really interested in hearing what other minimalists are getting away with. Grant it, I wouldn't show on a narrative set with just this kit, hahaha.
