The most dangerous kind of aluminum wire was mostly only used for residential wiring from ~’65-‘73 when copper was prohibitively expensive (Al alloys that are less dangerous were used with less frequency post-‘73, and Al is still a common material for transmission and distribution lines, and even some residential use like AC units or single branch circuits, but not very common in residential wiring). 

I charge a depreciated value for materials (see Greg's post) plus the full cost of labor.

And while I have an eye for design, I can also keep costs for finishes and other materials under control.
