Duster Rear Window Louvers

I would actually like some opinions on the finish of these....

I am getting prices for mild steel, aluminum and stainless from my laser cuter... for comparison more than anything.

For the mild steel I was going to get a number from a painter/powder coating source that we use. I know there's a recommended powder coating supplier for users of this website but shipping them all over will be costly... I don't know if colors will effect price but I also cant be responsible for colors not matching...

I can supply them in raw metal as well and you guys can find body shops to paint them... just wondering what you guys think...
