Can someone help me with this project

I want to make a flir camera that can see a detect a human 20 yards away in the dark with an air temp of 70 degrees for around 100 dollars.

LOL, sorry dude, but for $100 you won’t even be able to buy a visible light filter.
At two more zeros and then you’re in business.

Honestly, you are better off buying one..
