I have a 30x30 metal building. I have no windows. What would be the
best and cheapest way to air condition it? I thought about a window
unit but I have no windows

Window ACs work better when you don't waste a window on them. Most
come with optional cases meant for going through a wall, but you might
not need even that.

and not sure if cutting the corregated
metal would work right.

Depends on the construction. You can easily cut a hole, but supporting a big
enough AC will take some extra reinforcement. Add a couple of braces that
take the weight on the ground. In reality, all you have to do is cut an
opening the size of the ac, make a tray for it to rest on with legs secured
in the ground, both inside and outside if needed, put the AC into place.

This reminds me of how I installed an AC in a 5th floor window. I
was afraid it would fall out when in installed it or when I opened the
window, so I made shelf, well nailed (nails at opposite angles) to the
window sill, and supported on the cement ledge. Worked fine for the
small AC. If only I'd made it 20 inches deep instead of ten......

Next is air circulation. You may want to have a fan blowing the air around
inside as 30' is a long way to go. As for size, that depends on how much
insulation and ceiling height, etc. You may need two if you go for window
shakers. They will be 220V on the larger size too.

You can always go for a split system.
