In Germany this wouldn't be possible due to shortage of skilled workers. You'd have to settle with one who at least might have a bigger toolbox, but they wouldn't to an end-to-end analysis beforehand and would prefer to get the job done fast even if sluggishly. Recently I asked for quotes on adding a power socket to a din-rail fuse box.
