Help. Looking for a reasonable cost shear to cut 20g Copper Sheet

I am looking for a hobby level shear that could neatly cut 20 gauge Copper Sheet into smaller pieces. Actually, my cousin is looking for this for her artwork, but I would assume a lot of guys here might know what to look for.

I think she is only cutting up 1 square foot pieces into smaller pieces that can then be hand worked and trimmed, so I would think a high end paper style cutter, or some sheet metal cutting equivalent would work fine.

Any ideas or sources would be highly appreciated.

 

Eastwood or Harbour Freight should have something.
Doesn't take much to cut copper

 

Yeah I was thinking about Harbor Freight or maybe Northern Tool. I even thought a hard core college paper cutter would likely work. Any more tips would be appreciated.
