Here’s what I ended up doing.
10x10 pop up canopy with straight legs for $70 at Ace. Nice tent actually.
I attached the legs to 1x all around, then wrapped in plastic on 3 sides. 2 box fans mounted vertically blowing out the side door of the garage, garage door closed, back window open. A couple $15 5000 lumen led lights from Menards (one from above one on the side for flat light).
It barely fits in my garage but it would be nearly impossibly to have it work outside - too much wind for what is essentially a big kite.
I had the fans already, so this cost about $125 total.
