paint question

I am supplying paint.
I would do the block sanding after primer
door jambs under hood and trunk do not need painted as the color is the same
I drive my cars like this, beat them, break them, repeat process so the paint does not need to be show quality just look good.
I dont know what door rate is have not heard that term used.
the body shops all said no additional body work was needed .
My question more genneralized is that seems like alot for labor and was curious as to what kind of cost others have seen for this type of work.
