would have in the future

[efrem]

Hi! Could I use "would have" in reference to events in the future that, due to certain events in the past, will not be happening?

Had I not missed the plane, I would have made a huge sale at the tomorrow's trade show.

Or should it be:

Had I not missed the plane, I would make a huge sale at the tomorrow's trade show.

I'm not a teacher, but as I use and understand my native language, option number 1 is the only acceptable choice here. " Had I not missed the plane, I would have made a huge sale at the tomorrow's trade show."

Thanks. My inclination is also to use “would have”.
However, I read somewhere that “would have” should not be used in describing the future.
Also, considering the sentence
“Had I not missed my plane, I would be home by tomorrow morning”,
which I assume, perhaps mistakenly, to be correct, why don’t we use “would have” here? Should it be “would have been home”?
