Roll bender for aluminum tubing?

[calroy]

I am looking for a roll bender or similar for bending radii in aluminum tubing.

Material:
6061 T6 aluminum tubing or similar
.049", .065" wall thickness
.5", .75" and 1" O.D.

I want to form arches and compound curves ranging from 2' radius on up to 15' radius. This is for sculptural application.

Thank you for your time!
