Thanks for the suggestions! I should have specified slightly further:

I want a double crankset with the small ring having 38,39, or 40 teeth and the big ring with 46 or 48 teeth. ALSO, has to be available in silver (because a black crankset would look silly when every other component is silver on this build).

I know I'm probably just going to end up having to buy a crankset and switch out the rings, but I was hoping that maybe there is a ready made crankset out there that comes like this already that I don't know about.
