Shear cutter

I am in the photo industrie and looking for a foot shear to cut aluminum that is .045 17 gauge thick. I have been looking at
Grizzly G5772 Grizzly 52” Sheet Metal Shear
Baileigh FOOT STOMP SHEAR SF-5216E
16 Ga. x 52" Tennsmith Metal Cutting Air Shear, Mdl. A5216,
JET FS-1652J, 52" x 16 Gauge Foot Shear

the sheets will come in 48x48 inches to be cut in smaller sizes. Please help. Thank you

If that's all the metal you will be cutting, you might be able to find a big paper shear from a print shop going out of business. They will cut thin sheets of aluminum very precisely all day long as most are designed to clamp and cut a 6" thick stack of paper at a time.
