Any metal supply store will have crs.
Just look in the yellow pages for metal supply or metal fab.
Just make sure you dont get hot rolled steel as it has a scale on it that NEEDS to be removed before you do anything with it. Cold rolled closely matches the draw quality steel that the OEMs use.
A big supply place in chicago is Ryerson steel, they might even have 19ga, key word might...Eric

PS I just bought a 4x10 sheet of 18ga in KC it was 80 bucks and some change.
