The theta seems to be the winner for me (assuming I’d have to rob a bank for the last two suggestions)
So the list would be:
Theta S
Kodac q13 chart
ND gel
Luxmeter
Homemade balls

How would the linearlizing go? Linealizing the brackets first or linealize the HDRI? And I’m not shure how to read the information about the colors they provide “(20 steps in 0.10 density increments between0.0 and a practical printing black of 1.90 density)” what does that mean in float numbers? Do you guys know good tutorials about the process?

Edit:

What you’d do is shoot off a few shots of the chart on your camera and after you’d white balance the images from a mid grey, you can see if your camera stays neutral as it goes towards the darker and lighter patches. This is one way of getting some colour accuracy and also trying to keep your data linear.

So if I understand you correctly I’d shoot a image or take one of the brackets, propably the one in the middle and linealize this. And afterwards put the color corection I made onto the HDRI?
